Abstract :

The advanced cancer treatment for pediatric cancer has increased adult survivors of childhood cancer. These survivors have reduced bone mineral density (BMD) while beginning to age. Self-efficacy is crucial for enhancing individual health behavior in osteoporosis prevention. There is a paucity of valid and reliable scales to capture the self-efficacy for adolescents with cancer either in Taiwan or other countries. The purpose of this study was to develop and examine the psychometric properties of the Osteoporosis Prevention Self-Efficacy Scale � Adolescent Form (OPSES-AF). In the first stage, the content validity was established by six experts. In the second stage, confirmatory factor analysis (CFA) was performed. Data was collected from 120 adolescents who aged 13�20 and who were treated with cancer in the two medical centers from February to July 2015. The finalized OPSES-Af was a 7-item scale through CFA. Item responses were on a 5-point Likert scale ranging from 1 to 5 with total scores ranging from 7 to 35; higher scores reflected higher confidence to complete osteoporosis prevention activities. Construct validity was established through CFA that revealed a good fit of the model: RMSEA=0.042 and p value of RMSEA=0.51; NFI=0.96; NNFI=0.98; CFI=0.99; IFI=0.99; RFI=0.93. Cronbach�s alpha was 0.80. Guttman split-half coefficient was 0.80. Spearman-Brown coefficient was 0.81. The OPSES-AF showed appropriate results for describing the self-efficacy of osteoporosis prevention for adolescents with cancer.
