Effect of Major Depression on the Self-Image of Adolescent Boys and Girls

We investigated the specific impact of major depressive disorder (MDD) on the self-image of adolescent boys and girls seeking outpatient treatment. We used the Offer Self-Image Questionnaire (OSIQ) to compare 68 adolescents with MDD and 39 adolescents with no diagnosis of psychiatric illness according to the Structural Clinical Interview for DSM-III-R (SCID). Self-image among MDD patients was in general poorer than in the comparison group and was particularly expressed as dissatisfaction with life and an impaired mastery of the environment. Logistic regression analysis showed S2 (Emotional Tone) to be an independent factor associated with MDD (OR 1.15). In girls S2 was also independently associated with MDD (OR 1.14). The effect of MDD on self-image was more negative in girls than in boys and the self-image pattern differed between the sexes.     

Stability and Internal Consistency of the Offer Self-Image Questionnaire: A Study of Finnish Adolescents

Reliability of the Offer Self-Image Questionnaire (OSIQ) was assessed with two measures—internal consistency and stability—in Finnish children aged 13. The OSIQ was administered to 268 normal 13-year-old pupils (129 girls and 139 boys). Three weeks later, a third of the pupils (N = 88) were randomly selected for retesting. Eighty-three teenagers completed the questionnaire in an acceptable manner. The internal consistency of the test was verified for each scale using Cronbach . To estimate the stability of the test, Pearson correlation coefficients were calculated, and the mean raw scores for each scale were compared with those in the retest. The internal consistency of the test was fairly good ( = 0.54–0.84) for the majority of scales, except for scales S5 and S12 ( = 0.30–0.41). The stability of scales S1, S4, S5, S7, and S10 was good. On the basis of these two measures, we conclude that for Finnish adolescents, the OSIQ is sufficiently reliable only with respect to scales S1, S4, S7, and S10.
