Study of Functional Impairment in Students of Elementary and Secondary Public Schools in Iran.

OBJECTIVE

The current study aimed to investigate the frequency of impairment in different functional domains of life and the relationship between sex and age and functional impairment in school-based samples of Iranian children and adolescents.

METHOD

A sample of 270 children (ages 6-11) enrolled in two public elementary schools and a sample of 386 adolescents (ages 12-17) enrolled in four public secondary schools were selected by multistage sampling. The Persian version of the parent report form and self-report form of the Weiss Functional Impairment Rating Scale (WFIRS-P and WFIRS-S) were used for evaluating functional impairment in children and adolescents, respectively. Two-way analyses of variance (two-way ANOVAs) were conducted to explore the main effects and the interaction effect of sex and age on functional impairment.

RESULTS

11.9% of children and 29.5% of adolescents showed impairment in at least two functional domains of life. The most frequent impaired domain was life skills (22.6% of children and 30.3% of adolescents). While no significant sex and age effect was found during childhood, male adolescents showed more impairment in externalizing domains and female adolescents showed more internalizing difficulties. In addition, older adolescents showed more functional impairment relative to younger adolescents.

CONCLUSIONS

Detailed knowledge of the relationship between sex and age and functional impairment could be a starting point to target the major psychosocial elements of these challenges.
