Investigating reliability, validity and factor structur of parenting stress- short form in mother's 7-12 year- old child

Aim and The aim of current study was the investigating of factor structure, reliability, and validity of Parenting Stress Index- Short Form (PSI- SF) among Tehran city's mothers with children ages 7-12.Method and Materials: After translation, back translation, and adaptation pf instrument, due to normalization this instrument by applied survey design, 468 mothers with multiphase cluster sampling method fill in the PSI- SF. The data was analysis by structural equating model using Lisrel software. The results of Cronbach's alpha showed that the reliability quotients for parenting stress and each of sub scales of parental distress, parent- child dysfunctional interaction and difficult child were 0.90, 0.80, 0.84, and 0.80 respectively for total sample (these results for mothers of boys were 0.89, 0.80, 0.83, and 0.78 and mothers of girls 0.91, 0.80, 0.84, and 0.80). Test- retest reliability after 18 days showed 0.75 for total score, 0.82 for parental distress, 0.73 for parent- child dysfunctional interaction, and 0.71 for difficult child. We used DASS and CBCL to testing divergent, and convergent. By using Factor analysis, we extracted 3 factors (parental distress, parent- child dysfunctional interaction and difficult child).
