Age-independent effects of pubertal status on behavioral constraint in healthy adolescents.

ABSTRACT: Studies have examined age-related changes in personality traits from adolescence through young adulthood, finding that aspects of negative emotionality decrease while conscientiousness increases over time. Varied mechanisms may underlie these transitions, including puberty-driven hormonal changes. Here, healthy adolescents completed the Multidimensional Personality Questionnaire-Brief Form and self-report measures of pubertal status at baseline and after two years. Independent of age, pubertal status impacted primary trait scales of the MPQ-BF Constraint factor in a sex-specific manner. Females decreased in Constraint, and particularly Control, while males increased in Constraint, and particularly Harm Avoidance, with advancing puberty. Longitudinal analyses validated these findings for Control. Findings are discussed relative to males' versus females' achievement of optimal levels of behavioral control in adolescence.

Project description:IntroductionAdolescence is a distinctive period of life when intense physical, psychological, and cognitive development occurs. A healthy diet helps prevent various forms of malnutrition and non-communicable diseases (NCDs) like diabetes, heart disease, stroke, and cancer. The current study aimed to assess the change in behavioral intentions (measured based on the TPB) toward healthy dietary practices through health promotion intervention among adolescents studying in selected schools in an urban area of West Bengal, India.MethodsThe current study was a non-randomized controlled interventional study conducted among adolescents in either seventh, eighth, ninth, or tenth grades and aged between 12 and 16 years. Two-step cluster analysis with maximum likelihood estimation identified the intenders of a healthy diet. The intervention effect was measured using Relative Risk (RR) for being in the higher intention cluster through Generalized Linear Model (GLM) with a log-linear link under Poisson distribution assumptions and robust standard errors. A P-value of 0.05 or lesser was considered statistically significant.ResultsThere was no statistically significant difference in the mean score of "Attitude" in both groups. The mean score of "Subjective Norm" among the intervention group increased after intervention, and the difference was statistically significant. The mean score of "Perceived behavioral control" in the intervention group increased after the intervention, but the difference was statistically not significant. The intervention group's post-intervention proportion of intenders increased, and the difference was statistically significant. The relative risk of becoming an intender for healthy diet consumption in the Intervention group compared to the Control group was 2.07 (1.44-2.97).ConclusionsThe intervention package effectively brought about a positive change in behavioral intention toward healthy dietary practices among adolescents. Model-based and construct-oriented intervention packages can be adopted in school-setting to promote behavioral intention toward a healthy diet.
