psychometric evaluation of the short form of commitment to a plan of action scale for stretching exercise among the office employees based on hpm

Aims commitment to a plan of action key factors is critical for stretching exercise predicting. however, commitment to a plan of action in stretching exercise across the throughout working conditions is far difficult in iran; there is no measurement to evaluate commitment to a plan of action among workplace office employees. this study aimed at investigating the short form of confirmatory factor analysis commitment to a plan of action scale for stretching exercise predicting among based on health promotion model (hpm). materials & methods using multistage cluster sampling, 385 office employees from shahid beheshti university of medical sciences of iran were selected through on a short form of commitment to a plan of action scale. exploratory factor analysis (efa), confirmatory factor analysis (cfa) and cronbach’s alpha were also used.findings the mean age of the office employees was 39.4±7.76 years. cvi and cvr of each question were >0.7. the result of efa confirmed one factor or component with the main component technique (commitment to a plan of action) with 71.8% cumulative variance and kmo was 87.2% (p<0.001). this was the good fit index in cfa. the reliability was also explanatory. in the area of cfa, the result showed remsea=0.046, gfi=0.907, agfi=0.814, confirmed with cronbach’s alpha (α=85.8%) and [icc =0.74; 95% ci (0.62, 0.74)]. conclusion this study approved the short form of commitment to a plan of action scale for stretching exercise. however, more advice is provided to ensure a reliable and valid tool for realizing stretching exercise behaviors.
