[Comparison of mental health state and psychological capacities between college students with and without siblings].

OBJECTIVE: To compare the differences in mental health state and psychological capacities between Chinese college students with and without siblings. METHODS: The psychological status and capacities were evaluated with SCL-90, the Self-Esteem Scale, Spheres of Control Scale, Security Questionnaire and Cattell 16-PF Questionnaire in 427 college students, and among the students who presented valid responses, 139 with and 139 without siblings were selected for this comparative study. RESULTS: The total score and average score of SCL-90 in college students without siblings were significantly lower than those in students with siblings (P<0.05); the scores of factors C, E, and F of 16-PF were significantly higher but the score of factor O significantly lower in the former group (P<0.05). The scores of certainty in control, interpersonal security and total score of security were significantly higher in the students without siblings (P<0.01). CONCLUSION: The mental health state and some of the psychological capacities are generally better in college students with siblings than in those without siblings.
