Comparison of Body Mass Index by self-reported versus measured height and weight

This study compared differences between self-reported and measured height and weight and subsequent Body Mass Index. College students (N=62) were asked to complete a health questionnaire as accurately as possible. Height and weight were self-reported without the knowledge that these variables would be subsequently measured. Self-reported and measured heights, weights, and calculated Body Mass Indexes were statistically compared. Analysis indicated that measured height was significantly less than self-reported height for men, but weight was not significantly different. Calculated Body Mass Index for men was not significantly different, however, self-reported Body Mass Index resulted in placement in the Normal range (18.5 to 24.9) category and measured Body Mass Index placement in the Overweight category (25.0 to 29.9). Women's self-reported and measured heights were not significantly different; however, self-reported weight was significantly less than measured. Further, significantly different Body Mass Indexes were found for women. It was concluded that self-reported height and weight might be viewed with caution in Body Mass Index assessment for convenience samples of college-age subjects.     

Prevalence of weight reducing and weight gaining in adolescent girls and boys

This is a survey of the prevalence of weight reducing and weight gaining in high school children. Our sample of 1,373 high school girls and boys was geographically, racially, and economically diverse. On the day of the survey, 63% of the girls and 16.2% of the boys reported being on weight reducing regimens; 9.1% of the girls and 28.4% of the boys were trying to gain weight. Most female reducers and male gainers were already normal weight. Compared to other racial groups, whites and Hispanics were more likely to be reducing, whereas blacks were more likely to be gaining. Exercise and moderate caloric reduction were most popular for weight reducing, and a small but significant number were regularly using fasting, vomiting, laxatives, and appetite suppressants. The direction of weight modification for girls and boys conformed to stereotyped physical ideals. The rate of weight reducing in female high school adolescents has increased significantly since similar surveys of American youths 20 years ago.     

Self-esteem of adolescent girls as related to weight

The Rosenberg Self-esteem Scale was administered to 550 14- and 16-yr.-old (+/- 6 mo.) girls. Self-esteem scores were categorized by weight and weight by height. Scores on the Quetelet Index for obesity were correlated with self-esteem scores. Mean self-esteem of the low- and middle-weight by height group was significantly higher than the mean of the high-weight by height group. In analyzing weight alone, the self-esteem of the middle-weight group was significantly higher than the self-esteem of the high-weight group. The correlation of the obesity index and self-esteem indicated that as weight increased self-esteem decreased.     

Unhealthy weight control behaviours in adolescent girls: a process model based on self-determination theory

This study used self-determination theory (Deci, E.L., & Ryan, R.M. (2000). The ‘what’ and ‘why’ of goal pursuits: Human needs and the self-determination of behavior. Psychological Inquiry, 11, 227–268.) to examine predictors of body image concerns and unhealthy weight control behaviours in a sample of 350 Greek adolescent girls. A process model was tested which proposed that perceptions of parental autonomy support and two life goals (health and image) would predict adolescents’ degree of satisfaction of their basic psychological needs. In turn, psychological need satisfaction was hypothesised to negatively predict body image concerns (i.e. drive for thinness and body dissatisfaction) and, indirectly, unhealthy weight control behaviours. The predictions of the model were largely supported indicating that parental autonomy support and adaptive life goals can indirectly impact upon the extent to which female adolescents engage in unhealthy weight control behaviours via facilitating the latter's psychological need satisfaction.     

Self-reported mental problems in boys and girls: Preliminary findings

Previous research has reported higher frequency in boys than in girls of all psychopathological categories in childhood, and a reversal of the genders' ratio for adolescence and onwards. All studies about childhood mental health are based on referral by adults. The present study evaluated the prevalence of psychopathology in three age groups in childhood and adolescence, in both genders, using a new self-report scale of mental health problems for children and adolescents. Social desirability was measured separately. Five hundred sixteen school children in the fifth, seventh, and ninth grades were tested. Using the total mental health score, the study found that boys reported more disorders than girls in the two younger age groups, while the reverse was found in the oldest one. However, when social desirability was statistically controlled, the reversal phenomenon disappeared. In separate analyses of the subscales it was found that boys report more behavior problems, girls report more emotional problems in the youngest and oldest age groups, and both genders report an equal amount of school maladjustment. The results are discussed with regard to the importance of self-report and the control of social desirability.This study was conducted as an M.A. thesis in psychology by the first author, under the supervision of the second and third authors.     

Body image among adolescent girls and boys: a longitudinal study

This longitudinal study of adolescent girls and boys examined the contributions of social (peer appearance context), psychological (internalized appearance ideals and appearance social comparison), and biological (body mass) factors to the development of body dissatisfaction. Students (165 girls and 139 boys) completed questionnaires when they were either in 7th grade or 10th grade and again 1 year later. The results for the boys revealed a singular pathway to body dissatisfaction through internalized commitment to muscularity ideals. The prospective analyses of change in body dissatisfaction among the girls reflected the contributions of appearance conversations with friends, appearance social comparisons, and body mass. There was no evidence of mediation among the boys and limited support for it among the girls.     

Test-retest reliability and construct validity of Contour Drawing Rating Scale scores in a sample of early adolescent girls

Test–retest and construct validity of Contour Drawing Rating Scale (CDRS) scores were examined in 1056 Grades 7 and 8 girls. Questionnaires were completed four times, including retests at 2, 6 and 14 weeks. Test–retest reliability for current size, ideal size and current–ideal discrepancy mostly exceeded 0.70 (0.65–0.87, for the full sample, with higher rs for shorter retest periods). Ideal and current size ratings increased slightly over time. High correlations between perceived current figure and measured body mass index; moderate rs between current–ideal discrepancy and body dissatisfaction and restrained eating; and very low or no significant correlations with social desirability supported construct validity in this group. The study supported the use of the CDRS in early adolescent girls.     

Counselor preference and anticipated comfort ratings for a clinic sample of sexually abused versus non-abused girls

We compared counselor preference and anticipated comfort ratings for sexually abused and non-abused girls. Twenty-five sexually abused and 22 non-sexually abused girls between ages 7 and 17 participated in an initial psychological evaluation at a university outpatient clinic. Results obtained using the Counselor Preference and Comfort Survey revealed no significant difference between sexually abused and non-abused girls' ratings of their preference for male or female counselors and their anticipated comfort with male counselors; non-abused girls expressed significantly higher anticipated comfort with female counselors than did their abused counterparts. It was illustrated that younger girls', abused and non-abused, were more likely to prefer a female counselor and to anticipate being more comfortable with a female counselor. In addition, older non-abused girls were more likely to prefer a male counselor and more likely to anticipate being comfortable with a male counselor. Participants in both groups expressed a higher preference for and anticipated comfort with female counselors as compared with male counselors.     

Suicide as a resolution of separation-individuation among adolescent girls

The purpose of this study was to discover if there is a relationship between suicidal adolescent girls and borderline phenomena, and to examine separation anxiety in suicidal girls. Hansburg's Separation Anxiety Test and Gunderson's Diagnostic Interview for Borderline Disorder were administered to 40 adolescent girls. Only those girls that had attempted suicide were included in this study. The findings of this research suggested that adolescent suicide is a borderline phenomena that has its roots in the early separation-individuation phase of development, resulting in separation anxiety. The adolescent girl gets relief from the abandonment depression and feelings of separateness by using suicide as a vehicle for regression to a symbiotic state where she earlier had experienced safety.     

Risk factors for body dissatisfaction in adolescent girls: a longitudinal investigation

Because few prospective studies have examined predictors of body dissatisfaction--an established risk factor for eating disorders--the authors tested whether a set of sociocultural, biological, interpersonal, and affective factors predicted increases in body dissatisfaction using longitudinal data from adolescent girls (N = 496). Elevated adiposity, perceived pressure to be thin, thin-ideal internalization, and social support deficits predicted increases in body dissatisfaction, but early menarche, weight-related teasing, and depression did not. There was evidence of 2 distinct pathways to body dissatisfaction--1 involving pressure to be thin and 1 involving adiposity. Results support the contention that certain sociocultural, biological, and interpersonal factors increase the risk for body dissatisfaction, but suggest that other accepted risk factors are not related to this outcome.     

Self-reported versus behavioral self-handicapping: empirical evidence for a theoretical distinction.

The present study was an investigation of how Ss would respond when given 2 self-handicapping options, 1 behavioral (withdrawal of practice effort) and 1 self-reported (reporting high levels of stress). Ss anticipating a diagnostic test of intellectual ability were given different instructions regarding the effects of stress and practice on test performance. Ss were told that (a) stress only, (b) practice only, (c) both stress and practice, or (d) neither stress nor practice affected test scores. Ss were then given the opportunity to self-report a handicap on a stress inventory and to behaviorally self-handicap by failing to practice before the test. High self-handicapping men and women showed evidence of self-reported handicapping, but only high self-handicapping men behaviorally self-handicapped. However, when both self-handicaps were viable, both high self-handicapping men and women preferred the self-reported over the behavioral self-handicap.     

Effects of body fat on weight concerns, dating, and sexual activity: a longitudinal analysis of black and white adolescent girls.

Using data from a 2-year longitudinal study of 200 Black and White adolescent girls (mean age was 13.8 years at study entry), the authors investigated the implications of differences in body fat for dating and sexual activity and the implications of heterosexual activity for dieting and weight concerns. Among White girls, and Black girls with college-educated mothers, more body fat was associated with a lower probability of dating, even among nonobese girls. However, dating and sexual experience were unrelated to subsequent dieting and weight concerns. For both Blacks and Whites, body fat was the key determinant of dieting, weight dissatisfaction, and eating concerns. These findings indicate that adolescent girls' concerns about weight have a basis in real experiential differences, and efforts to promote healthy attitudes and eating habits may be more effective if the experiential implications of weight differences are taken into account.     

Effects of a weight maintenance diet on bulimic symptoms in adolescent girls: an experimental test of the dietary restraint theory.

It is widely accepted that dieting increases the risk for bulimia nervosa, but there have been few experimental tests of this theory. The authors conducted a randomized experiment with adolescent girls (N=188) to examine the effects of a weight maintenance diet on bulimic symptoms. A manipulation check verified that the diet intervention resulted in weight maintenance and significantly reduced the risk for obesity onset and weight gain observed in assessment-only controls. As hypothesized, the diet intervention resulted in significantly greater decreases in bulimic symptoms and negative affect than observed in controls. These experimental findings, which converge with those from a weight loss diet experiment, appear antithetical to dietary restraint theory and suggest instead that dietary restriction curbs bulimic symptoms.     

Developing internality and perceived competence: the empowerment of adolescent girls

A small group workshop, developed for Big Sisters of Colorado, Inc. to complement their traditional program, was evaluated to determine its effectiveness for working-class and underclass adolescent girls. The "Life Choices" program was successful with working-class Ss, resulting in increased internality and perceived competence for school success, social relationships and general life events. These Ss also increased their knowledge of both traditional and non-traditional career alternatives. However, the program did not succeed with underclass adolescent girls, who showed no increase in internality or knowledge of career alternatives and reported a significant decrease in perceived competence after completing the same program. It is suggested that the goals and strategies presented in such programs must be designed specifically for adolescents of different backgrounds if they are to result in empowerment of the participants.     

Incarcerated adolescent girls: personality, social competence, and delinquency

The aim of this study was to gain greater insight into the relationship of delinquency to personality and social competence in incarcerated girls. It was hypothesized that agreeableness and conscientiousness would correlate negatively with delinquency, and that the sensation-seeking aspect of extroversion would correlate positively. Two theoretical views were used to predict the relationship between social competence and delinquency: (a) delinquency as an expression of lack of social competence (i.e., social deficit), and (b) delinquency as socially competent and rationally analyzed behavior. The first view implies a negative correlation between delinquency and social competence, while the second indicates a positive one. The participants were thirty-three 12- to 18-year-old incarcerated girls. An adaptation of the Self-Reported Delinquency Scale was used for measuring delinquency; personality was measured using the Five-Factor Personality Inventory; and the Scale for Interpersonal Behavior was used to measure social competence. Agreeableness was not found to correlate with the overall delinquency score or with any specific type of delinquency or crime. The more crimes the girls reported, the less conscientious they were, and the more neurotic and open they were. The correlation between delinquency and extroversion was not statistically significant. A higher level of delinquency was accompanied by higher social competence when negative self-assertion was required (i.e., a low level of tension was felt in expressing negative feelings that were appropriate to the situation). In other social situations, however, the girls reported more situation-inappropriate feelings of tension. It was concluded that some personality factors and aspects of social competence can predict delinquency.     

Daily and trait rumination: diurnal cortisol patterns in adolescent girls

Rumination is a maladaptive form of emotion regulation associated with psychopathology. Research with adults suggests that rumination covaries with diurnal cortisol rhythms, yet this has not been examined among adolescents. Here, we examine the day-to-day covariation between rumination and cortisol, and explore whether trait rumination is associated with alterations in diurnal cortisol rhythms among adolescent girls. Participants (N?=?122) provided saliva samples 3 times per day over 3 days, along with daily reports of stress and rumination, questionnaires assessing trait rumination related to peer stress, and diagnostic interviews assessing depression and anxiety. Greater rumination than usual during the day was associated with lower cortisol awakening responses the following morning, but this effect was not significant after accounting for wake time and an objective measure of adherence to the saliva sampling protocol. Trait rumination was associated with lower average cortisol levels at waking and flatter diurnal slopes, accounting for wake time, protocol compliance, and other factors. These patterns may help to explain why rumination is related to the development of psychopathology.
