From the * Children's Hospital Medical Center and Objective. Eliminating health
disparities, including those that are a result of socioeconomic status
(SES), is one of the overarching goals of Healthy People 2010. This
article reports on the development of a new, adolescent-specific
measure of subjective social status (SSS) and on initial exploratory
analyses of the relationship of SSS to adolescents' physical and
psychological health.
Methods. A cross-sectional study of 10 843 adolescents
and a subsample of 166 paired adolescent/mother dyads who participated
in the Growing Up Today Study was conducted. The newly developed
MacArthur Scale of Subjective Social Status (10-point scale) was used
to measure SSS. Paternal education was the measure of SES. Indicators of psychological and physical health included depressive symptoms and
obesity, respectively. Linear regression analyses determined the
association of SSS to depressive symptoms, and logistic regression determined the association of SSS to overweight and obesity,
controlling for sociodemographic factors and SES.
Results. Mean society ladder ranking, a subjective measure
of SES, was 7.2 ± 1.3. Mean community ladder ranking, a measure
of perceived placement in the school community, was 7.6 ± 1.7. Reliability of the instrument was excellent: the intraclass correlation
coefficient was 0.73 for the society ladder and 0.79 for the community
ladder. Adolescents had higher society ladder rankings than their
mothers (µteen = 7.2 ± 1.3 vs
µmom = 6.8 ± 1.2; P = .002). Older adolescents' perceptions of familial placement in society
were more closely correlated with maternal subjective perceptions of
placement than those of younger adolescents (Spearman's rhoteens
<15 years = 0.31 vs Spearman's rhoteens Conclusions. This new instrument can reliably measure SSS
among adolescents. Social stratification as reflected by SSS is
associated with adolescents' health. The findings suggest that as
adolescents mature, SSS may undergo a developmental shift. Determining
how these changes in SSS relate to health and how SSS functions
prospectively with regard to health outcomes requires additional
research.

years = 0.45; P < .001 for both). SSS
explained 9.9% of the variance in depressive symptoms and was
independently associated with obesity (odds
ratiosociety = 0.89, 95% confidence interval = 0.83, 0.95; odds ratiocommunity = 0.91, 95%
confidence interval = 0.87, 0.97). For both depressive symptoms
and obesity, community ladder rankings were more strongly associated
with health than were society ladder rankings in models that controlled
for both domains of SSS.
The elimination of health disparities among
different population segments, including differences related to
socioeconomic status (SES), is the second overarching goal of Healthy
People 2010. Recently, the American Academy of Pediatrics also
recognized and highlighted the importance of addressing SES as an
causative agent in the creation of health differentials and called for
additional research to understand the impact of SES across the life
course.1
The inverse, graded relationship between SES and infant, child, and
adult health is well established.2-11 However, among
adolescents, the SES gradient in health is present inconsistently.12-15 A number of models have been
proposed to explain the different patterning of SES effects on
adolescent health.2,16 Choosing the most appropriate
model(s) has been hampered by 2 major barriers. First is the lack of
understanding of the mechanisms underlying the SES-health
relationship, in general. Second, there is a lack of youth-specific
indicators of social status. A new, youth-specific measure of
subjective perceptions of social status Although income, education, and occupation (the traditional
variables used to measure SES) are only moderately correlated with each
other, all are associated with health in a similar manner. This
suggests that all 3 individually reflect an underlying common component
of social status.17,18 Although the SES gradient in health
has been studied widely, how social status causes poorer health is not
clear. This may be, in part, because social status has been defined as
SES, which is an external, purely objective measure that does not
account for subjective, internalized perceptions of social status.
Wilkinson19,20 argued that these subjective perceptions of
relative ranking may be more important determinants of health than
objective indicators, such as income, which assess material
resources.21
Despite the vast literature on SES's effects on health, little is
known about people's perceptions of their placement in the social
hierarchy, what determines these perceptions, or how these perceptions
relate to health. This is true for both adults and adolescents.
Research has been hampered by a lack of indicators of subjective social
status. Studies have relied, instead, on measures of social class
identification and have focused on political and cultural attitudes and
behavior.22-30 Almost none have looked at health. Two
major problems exist with the use of class identification as a proxy
for social status. The categorical nature of the measures of social
class identification does not adequately tap the full spectrum of
socioeconomic stratification. In addition, socially charged language is
used to describe the discrete classes. Social desirability may be
figuring prominently in an individual's choice of middle versus upper
class, working versus lower class. The MacArthur Scale of Subjective
Social Status was developed to address these problems and assess
perceived placement within the social hierarchy among adults by using a
visual scale.18 The instrument is a drawing of a ladder on
which people place themselves. The instrument has 2 parts, 1 linked to
traditional SES indicators (a ladder assessing placement in society)
and 1 linked to standing in a more local, immediate social environment (a ladder assessing placement in community). These ladders have been
used in several studies among adults, and results suggest that ladder
rankings are more powerful determinants of health-related outcomes than
traditional measures of SES.18,31,32 Whether similar
associations might be shown at different stages in the life course,
including adolescence, has not been tested.
Adolescence is a critical developmental period to study with regard to
social stratification and the sociobiologic translation. During
adolescence, the transition between social status of childhood, which
is determined primarily by familial social status, and adult social
status, which is more self-determined, occurs and an individual's perceptions of social stratification crystallize. Health indicators of
infants and young children, such as infant mortality and immunization status, used in studies of social determinants of infant and child health, reflect parent-based social inequalities in health and, often,
parental beliefs and behaviors, as well. As an adolescent's self-conceptualization matures, perceptions of social status may be
based on both parental SES and the adolescent's sense of his or her
own standing. In addition, beliefs, behaviors, and physiologic changes
that develop in adolescence have great potential to have an impact on
health. Thus, it is likely that differences between family
(parent-based) measures and self (adolescent-specific) measures would
develop during the teenage years. The lack of a consistent graded
effect of SES on adolescent health may be because most analyses that
assess the SES-health gradient among adolescents use parental measures
of SES, which do not tap the adolescent's emerging self-concept of
social stratification.33
To address the need for a youth-specific indicator of subjective
social status, we modified the MacArthur Scale of Subjective Social
Status to be applicable to adolescents. We did this because use of the
adult scale, which asks the individual to place him- or herself
relative to others in American society with regard to education,
income, and occupation, is not appropriate for adolescents, the vast
majority of whom are still in school, are not financially independent,
and are not employed full time.
Like its adult counterpart, this instrument has 2 ladders (Fig
1). The first ladder assesses familial
placement in US society and is meant to parallel the adult ladder
assessing personal placement within society. This ladder is a measure
of subjective SES. Comparisons between adolescent and adult responses to this ladder are meaningful as both the adult and adolescent society
ladders anchor the ladder to the same reference group: US society. The
second ladder assesses personal placement in the school community. It
has been suggested that social status among peers is of equal or
greater importance to the SES-health relationship among adolescents as
parental social status. Glendinning et al34 found that the
pattern of social integration was associated with health behaviors such
as smoking and drinking independent of social class background. Given
the rise in meaning of peers to an adolescent's self-concept as they
mature, it is important to explore the relationship between social
status in a community of peers. The school community ladder fulfills
this need for in-school youths. Because this ladder specifies the
school community as the reference group, the youth version of this
ladder is not consistent with the adult instrument, which asks
individuals to define community "however it is meaningful to you."
Some adults use their neighborhood as the reference, others use their
work, and still others use friends. Therefore, comparisons between
adult and youth responses to the community ladder should be interpreted
with this difference in mind. The youth version of the MacArthur Scale
is easy to comprehend and is appropriate for those in grade 7 and
higher, approximately age 12 and older.
the MacArthur Scale of
Subjective Social Status-Youth Versionallows us to address both of
these barriers and assess the effects of social status among
adolescents using a broader conceptualization of this construct. This
article describes the development and initial testing of the MacArthur
Scale of Subjective Social Status-Youth Version and discusses
implications for future research on unraveling the mechanisms behind
socioeconomic disparities in health.

INITIAL HYPOTHESES RELATING SUBJECTIVE AND OBJECTIVE SOCIAL STATUS TO ADOLESCENT HEALTH |
|---|
On the basis of the literature regarding social class identification, social stratification, and the SES gradient in health, we developed 3 initial hypotheses about the relationships between objective and subjective social status and health among adolescents. First, we hypothesized that adolescents' perceptions of family standing within society will be higher than maternal perceptions of social status within society. Second, we hypothesized that as adolescents age, there will be less upward bias in their perceptions of social status. Therefore, older adolescents will have lower perceptions of social status with regard to familial placement in society than younger adolescents, and concordance between adolescent and maternal scores on the society ladder will be greater among older than among younger adolescents. These 2 hypotheses are based on the earlier work of Centers,29 which showed that adolescents' perceptions of stratification tend to be more optimistic than those of adults and that this tendency toward upward identification lessened with increasing age. Last, we hypothesized that SSS, especially the school community ladder, will be associated with indicators of adolescent's physical and mental health independent of the effects of traditional, family-based measures of SES. This hypothesis represents an early assessment of the relationship of perceptions of social status to health outcomes and of whether subjective assessments of stratification are more powerful predictors of health than objective measures of SES. To test this hypothesis, we identified 2 specific health outcomes that represent significant morbidities among adolescents, have been associated with SES, and were assessed in the cohort that we studied (see below) as our health indicators.12 These included depressive symptoms and obesity. Depression is a serious morbidity among adolescents and carries with multiple sequelae, including poor school performance, lower self-esteem, suicidal tendencies, and substance use.35 Large epidemiologic studies, such as the Growing Up Today Study (GUTS), assess depressive symptoms rather than perform diagnostic interviewing. Obesity is an increasing, important public health problem throughout the life course and carries multiple medical and psychologic sequelae.36-38 More than half of the adult US population older than 19 years is overweight or obese.39 Twelve percent of adolescents are obese, defined as having a body mass index (BMI) >95% for age and gender.40 Overweight adolescents with a BMI between the 85% and 95% are considered at risk for obesity, and obesity during adolescence is an extremely powerful predictor of obesity during adulthood.41,42 Data from multiple national surveillance studies documented a significant increase in the prevalence of overweight and obesity in the past decade.3943-45

Study Samples
Evaluation of reliability of the MacArthur Scale of Subjective Social Status-Youth Version and testing of these initial hypotheses were performed using 2 large, established cohort studies: GUTS and the Nurses' Health Study II (NHSII). GUTS, which was initiated in 1996, involves more than 16 000 children of mothers who are participating in the ongoing NHSII, a prospective cohort study involving 116 671 female registered nurses aged 25 to 42 at the initiation of the study in 1989. Details of both the NHSII and GUTS have been reported elsewhere.46,47 The MacArthur Scale of Subjective Social Status-Youth Version was added to GUTS in 1999. That year, a total of 10 843 participants returned the long form of the survey, which contained the MacArthur Scale of Subjective Social Status-Youth Version;; 58.9% were female (n = 6382), and 54.9% (n = 5840) were younger than 15 years. Mean age was 14.4 ± 1.6 years. The cohort was primarily white (93.3%), which reflects the demographics of the nursing population.
In addition to the entire 1999 GUTS cohort, 2 subsamples were derived to evaluate the instrument and to test the hypotheses: an adolescent subsample and a mother subsample. The adolescent subsample was used to assess test-retest reliability. A random sample of 184 adolescent who responded to the 1999 survey were sent the MacArthur Scale of Subjective Social Status-Youth Version approximately 2 months after the 1999 survey was distributed; 115 returned the instrument (62.5% response rate). There were no significant differences in age or gender among those who responded to the retest and those who did not.
Maternal responses to the adult version of the MacArthur Scale of Subjective Social Status were needed to address the first and second hypotheses. In addition, we wanted to explore how well the only measure of SES in the NHSII, partner education, assessed SES in GUTS. To accomplish these tasks, we mailed to a random sample of mothers of 194 of the 1999 participants a questionnaire that included the MacArthur Scale of Subjective Social Status-Adult Version and questions assessing 1998 household income, maternal education, and nursing degree. Because surveys were mailed and returned within a few-month period, making 1999 income variable depending on when the survey was completed, 1998 household income was assessed; 166 of the 194 mothers returned these surveys, for a response rate of 85.6%. There were no significant differences in age, gender, partner education, MacArthur Scale of Subjective Social Status-Youth Version ladder rankings, or health indicators for the 166 adolescents whose mothers responded compared with the overall 1999 GUTS population. Responses from the 166 mothers were paired with their child's response to the 1999 survey to test hypotheses.
Variables Used in Analyses
Adolescents' SSS The MacArthur Scale of Subjective Social Status-Youth Version was used to assess SSS among adolescents (Fig 1). This newly derived instrument had excellent 2-month test-retest reliability among the subsample of 115 1999 GUTS respondents (Table 1). In general, reliability of the community ladder was higher than that of the society ladder. This suggests that adolescents are more consistent in placing themselves within their more immediate social environment than they are at placing their families within the broader social context.
|
Adults' SSS The adult version of the MacArthur Scale of Subjective Social Status was used in the mothers' subsample to assess SSS.18 This instrument assesses current subjective perceptions of social status.
SES Because these analyses place the adolescent in the context of his or her current environment, sociodemographic factors of the resident, although not necessarily biological parent(s) or parental figures, are considered here. As mentioned above, no direct individual- level indicators of SES were obtained in GUTS. Mothers of GUTS participants are surveyed every 2 years because they are participants in the NHSII. In 1999, the NHSII asked participants to report current partner or spouse's education, hereafter referred to as "father's education." Current partners and spouses of the NHSII participants are not surveyed directly by either the NHSII or the GUTS. By merging NHSII and GUTS data on a common maternal identifier, we determined that father's education was missing for only 8.8% (n = 953) of the 1999 GUTS respondents. Half of those for whom father's education was missing lived in single-parent families. There was no difference in community ladder rankings among GUTS participants whose mothers did not report father's education compared with those whose mothers did report father's education. However, adolescents whose mothers reported father's education had higher society ladder rankings than those who did not (P < .001). Consistent with the design of GUTS, mothers' report of father's education showed that GUTS is a socioeconomically advantaged cohort: 32.3% of partners had graduate training, 29.8% had a 4-year college degree, 16.8% had attended a 2-year college, 16.1% had a high school degree, and 0.5% had less than a high school education.
To determine whether father's education adequately assessed SES in the 1999 GUTS cohort, we asked the mother subsample (n = 166) to report household income in 1998, maternal education, and maternal nursing degree. Father's education was correlated with maternal education (Spearman's rho = 0.22; P = .005), nursing degree (Spearman's rho = 0.23; P = .005), and household income (Spearman's rho = 0. 26; P < .001) to the same degree and, therefore, seemed to assess SES adequately. Thus, father's education, which was present for almost the entire GUTS cohort, was used as the indicator of SES in this study. We used the mean of the mother's education among those in the mother's subsample who lived in a single-parent household as the value of father's education for GUTS participants who lived in families with a single mother as the parent.Health Indicators
Depressive Symptoms
GUTS contains 6 Likert-type scale items that assess depressive
symptoms, such as feeling worthless or depressed, which were based on
the McKnight Risk Factor Survey.48 These were summed to
create a scale that could range from 6 to 30. Higher scores indicate
fewer depressive symptoms. The scale had good reliability (Cronbach's
= 0.73). Mean in the 1999 GUTS cohort was 22.8 ± 3.5.
Obesity
GUTS participants self-reported height and weight. BMI
(kg/m2) was calculated from these self-reported
measures. BMI from self-report of height and weight has been shown to
be a valid method of determining obesity among
adolescents.49 Overweight was defined as BMI 
85% for
age and gender and obesity as BMI 95% for age and
gender.41,50 The prevalence of overweight in this cohort
was 20.3% and of obesity was 6.1%.
Covariates
Sociodemographic covariates used in multivariate analyses
included age, gender, race (white vs nonwhite), and number of parents in the home. In addition, the relationships between social status and 2 psychological covariates that may have an impact on adolescents' self-perception were assessed. These included self-esteem and popularity. Self-esteem and popularity were assessed by a modified version of the Harter Self-Perception Profile for
Children.51 This instrument has been included in the GUTS
survey yearly since the cohort's inception. The modifications of the
Harter scale were based on extensive pilot testing among students in
public schools in Salem, Massachusetts. The scale contains a 6-item
assessment of global self-worth (Cronbach's = 0.85) and a
6-item assessment of social acceptance, a measure of popularity
(Cronbach's = 0.77).
Data Analyses
Statistical analyses were performed using SAS (SAS Institute, Inc, Cary, NC). Test-retest reliability was assessed with intraclass correlations.52 For depressive symptoms, stepwise linear regression analyses were performed to assess the relationship between ladder responses and depressive symptoms, controlling for age, gender, number of parents in the home, and father's education, and psychological covariates. A baseline model with sociodemographic covariates was run first. Then, ladder rankings were added individually to the baseline model to assess the amount of additional variance that each ladder explained. Next, ladder rankings were added together to the baseline model to determine whether each independently predicted depressive symptoms. This entire process then was repeated with both sociodemographic and psychological covariates in the baseline model to provide a more stringent test of the discriminant validity of the ladders. For overweight and obesity, individual and combined logistic regression analyses controlling for all covariates were performed. Because mental and physical health may be related, these analyses also controlled for depressive symptoms in addition to self-esteem and popularity. Odds ratios and 95% confidence intervals associated with a 1-point change in the ladders are reported.
Because of the theoretical importance of age in the development of perceptions of social status, a ladder × age interaction was assessed in all multivariate analyses. To determine whether gender was an important modifying factor, we also tested for ladder × gender interactions. No significant interactions were found in either linear or logistic regression modeling, so none are reported. Because 22.3% of families in GUTS had more than 1 child enrolled in the study, multivariate analyses were performed using generalized estimating equations to account for intrafamilial clustering among siblings.53 This analytic technique takes into consideration in the regression analyses family effects that result from this clustering.

Description of SSS Among Adolescents
Mean society ladder rank was 7.2 ± 1.3, and mean community
ladder rank was 7.6 ± 1.7. Responses ranged from 1 to 10 for both ladders. Nonresponse rates among the adolescents were very low for
these items: approximately 2%. There were no significant gender differences in perceptions of familial placement in society. However, girls' perceptions of personal placement within the school community were significantly higher than boys' (µgirls = 7.7 ± 1.6 vs µboys = 7.5 ± 1.8;
P < .001). The Spearman rank correlation between adolescent and maternal society ladder responses was 0.38 (P < .001). Although significant, the moderate degree
of this correlation suggests that maternal and adolescent perceptions
of standing within society differ considerably, which supports the
theorized differences between adolescent- and parent-based measures. In addition, the correlation between adolescent and maternal responses to
the community ladder was very weak (Spearman's 
= 0.13;
P < .01). This may reflect the different language
anchoring of this ladder between adolescent and adult versions
mentioned above. Looking at within-person correlations between the
society and school community ladder responses reveals that the ladders
are tapping 2 distinct domains of social status. For adolescents, the
Spearman rank correlation between society and community ladders was
moderate at 0.35 (P < .001). The correlation between
society and community ladders was stronger for the mothers (Spearman's = 0.61; P < .001), suggesting that
perceptions of standing in reference to different social environments
becomes more similar as individuals mature. The correlation between the
adolescent's society ladder ranking and father's education was weak
(Spearman's = 0.21; P < .01), indicating, as
hypothesized, that objective and subjective SES are different
components of social status.
Analyses Assessing Potential Developmental Changes in SSS
As hypothesized, adolescents tended toward higher society ladder
rankings compared with their mothers (µteen = 7.2 ± 1.3 vs µmom = 6.8 ± 1.2;
P = .002). Correlational analyses also showed that the
strength of the correlation between adolescent and maternal society
ladder rankings increased with age (Spearman's rho = 0.31 among
those younger than 15 and Spearman's rho = 0.45 among those 15 years or older). Although striking, this difference was not statistically significant. Younger adolescents did have significantly higher perceptions of familial placement in society than older adolescents (µteens <15 years = 7.3 ± 1.3 vs µteens 15 years = 7.2 ± 1.2; P < .001). Age was not
significantly associated with adolescents' responses to the school
community ladder. Last, reliability of both ladders is higher among
older adolescents, suggesting that the ability to define and accurately
report subjective perceptions of social status stabilizes with
increasing age.
Associations of the MacArthur Scale of Subjective Social Status and Indicators of Adolescents' Mental and Physical Health
The results of regression analyses to assess the associations between SSS and depressive symptoms, controlling for SES and other covariates, revealed that higher SSS was associated with fewer depressive symptoms (Table 2). When sociodemographic characteristics were controlled for, as hypothesized, the school community ladder was more strongly associated with depressive symptoms than the society ladder. The community ladder explained an additional 9.5% of the variance in depressive symptoms, whereas the society ladder explained an additional 4.4%. In the combined model, both ladders were significantly associated with depressive symptoms and together explained an additional 9.9% of the variance. The community ladder remained more strongly associated with depressive symptoms than the society ladder in this model.
|
Although both ladders remained significantly associated with depressive
symptoms when controlling for self-esteem and popularity, the strength
of the association was reduced greatly (Table 2). In the combined model
controlling for sociodemographic and psychological covariates, both
ladders explained an additional 1.7% of the variance in depressive
symptoms. Self-esteem was the factor most strongly associated with
depressive symptoms in the final model
(
self-esteem = 4.65; P < .001).
Table 3 presents odds ratios and 95% confidence intervals for ladder rankings and father's education in relation to overweight and obesity when controlling for covariates and depressive symptoms. In individual models, SSS and SES were significantly associated with both overweight and obesity in the expected direction. Higher social status was associated with a decreased likelihood of overweight and obesity. The odds ratios for the society and community ladders were almost identical, indicating that the magnitude of the effect of the ladders was virtually the same with regard to obesity. However, society ladder rankings became nonsignificant in the combined model, whereas the community ladder maintained an independent effect. It is interesting to note that the odds ratio for father's education changed very little in the combined model. Thus, these data do not suggest that the effect of objective SES is mediated through SSS but rather that these domains of social status are independently associated with overweight and obesity.

This article reports on a new, adolescent-specific measure of SSS.
The development of this indicator follows the American Academy of
Pediatrics recommendation that "pediatric investigators, in
collaboration with social scientists, should develop and apply research
methodologies that will result in careful definitions of, analysis of
interactions among, and ultimately documentation of the effects of
these variables (gender, race/ethnicity, and SES) on child
health."1 The purpose of this article was to introduce a
method for defining social status more fully by providing a
youth-specific measure of SSS. When used in conjunction with
traditional measures of SES, this new instrument will allow investigators to broaden their analyses of the effects of social status
on adolescent health. Our findings indicate that the MacArthur Scale of
Subjective Social Status-Youth Version is a reliable measure of SSS
and that both dimensions of SSSperceptions of familial placement in
society and personal placement in the school communitycorrelate with
health indicators independent of the effect of a traditional measure of
SES.
Data from the United Kingdom led West54 to argue that adolescence represents a time when there is an "equalization" in health among varying SES groups and that health differentials reemerge during adulthood when SES rises in importance in determining one's self-concept. In later adolescence and early adulthood, when experience with society broadens and exposes individuals to the wider social stratification present in society and an individual's self-concept matures, SES differentials in health reemerge, perhaps through physiologic changes or a shift in health-promoting or risk-taking behaviors. Our finding that younger adolescents have higher perceptions of placement within society supports this theory. In addition, we found much stronger correlations between the society ladder and father's education among adolescents 15 years of age or older compared with those younger than 15 years. The difference suggests a developmental evolution in SSS. As adolescents age and mature cognitively, their perceptions of social stratification also may mature. Older adolescents, because of an increased ability to think abstractly, may be better able to define and reliably report perceptions of social stratification. Thus, subjective perceptions of social status among older adolescents will align more closely with parental perceptions of social status. Future research on social inequalities in health should consider assessing this developmental shift in design and analytic strategies.
The moderate correlations between the society and school community ladders demonstrated in this study support the hypothesis that SSS has 2 components: 1 linked to perceptions of familial placement within American society and 1 linked to individual placement in the school community. The ability to explore how different societal reference groups affect health is a unique innovation of the MacArthur Scale of Subjective Social Status. We hypothesized that the school community ladder would be particularly important in capturing a key aspect of social stratification among adolescents. In part, this is because it is likely that family SES is less salient for adolescents than placement within society is for adults. In addition, peer norms, perceptions, and behaviors are important determinants of adolescents' health and well-being. These may be reflected in the school community ladder. The school community ladder was strongly associated with both popularity and global self-esteem in these youths. We also found that the school community ladder was more strongly associated with both depressive symptoms and overweight/obesity among adolescents than the society ladder in cross-sectional analyses. When we controlled for self-esteem and popularity, the relationships between school community ladder rankings and health indicators remained significant. This suggests that objective and subjective social status both may have direct and indirect effects on these health outcomes. Further research is needed to understand how subjective perceptions of social status affect health prospectively and the interplay between stratification within the local community and stratification within society at large in the creation of health differentials. In addition, further research will help to elucidate the factors underlying adolescents' perceptions of stratification both in the local community and within society at large.
There are some limitations of these data that must be acknowledged. Although the measure of depressive symptoms in this study was related to SSS, it was not significantly associated with father's education. This measure of depressive symptoms, although adapted from a scale validated for use in adolescent girls, is not standardized and is not validated for use among adolescent boys.48 Thus, the lack of association between father's education and depressive symptoms could be due to measurement error. However, this lack of association also could be due to the truncated distribution of father's education in this cohort. GUTS is a study of the children of nurses. By its very design, the sample is primarily white and is skewed to the upper end of the SES gradient. This limits generalizability of the results. The limited variance in father's education also may increase the relative power of subjective status compared with objective indicators, although we did find that father's education was associated with overweight and obesity and that the magnitude of the association was similar to that from a larger, more representative sample of adolescents.12 Last, as stated above, these data are cross-sectional and therefore do not establish causality. Because these data are cross-sectional, we could not determine whether low popularity or self-esteem led to lower perceptions of standing or whether low perceptions of standing cause social isolation and poor self-concept. By controlling for these psychological states, the analyses demonstrate a direct effect of SSS. They do not assess whether SSS indirectly creates health inequalities by creating lower self-esteem, more social isolation, increased depressive symptoms, and more obesity. These analyses also do not assess whether depression and obesity cause lower perceptions of social status, a social drift hypothesis. The possibility of reverse causation and social drift is most relevant to the school community ladder among adolescents. Despite this possibility, these analyses did continue to show a direct effect of subjective social status. In addition, it should be noted that among adults, some have suggested a social drift hypothesis with regard to the genesis of the SES gradient in health.55 However, studies do not support the social drift hypothesis but do support social causation.56

The current research suggests that social stratification as reflected by subjective social status may be an important determinant of adolescents' health independent of traditional measures of SES. In this cross-sectional sample of adolescents from primarily non-Hispanic white, relatively high-SES families, the MacArthur Scale of Subjective Social Status-Youth Version proved to be a reliable indicator that can be used to assess adolescents' perceptions of social stratification and link these perceptions to health outcomes. Additional research using this instrument can increase understanding of developmental changes in perceptions of social status. In this way, researchers will be able to define more fully and precisely the effects of social status on adolescent health. In addition, researchers will be able to use this instrument to increase understanding of how social status influences risk and resilience during the critical developmental period of adolescence by opening up fresh avenues for exploring socioeconomic differences in health. These include understanding the health consequences of discrepant rankings and linking both objective and subjective components of social status to potential biological mediators of the SES-health gradient.
