Reliability    &    Validity

Reliability of the CD
MP
  • Cronbach’s Alpha internal-consistency reliability for the eleven scales (3 items each) of the CDMP questionnaire for the Internet version in English (N=208) ranged from .71-.89 (median = .79).
  • For the Hebrew paper & pencil version (N=285), the median Cronbach’s α internal-consistency reliability of the 11 CDMP scales was .81 (range .72 to .92)."
  • Cronbach’s Alpha internal-consistency reliabiliy for the 11 scales (3 items each) of the CDMP questionnaire for the Internet version in Hebrew (N= 431) ranged from  .74-.91 (median = .81)

Test-Retest Estimates

  • T1-T2 (4-months gap) correlations of the CDMP Hebrew version (N= 212) ranged from .48 (for consultation with others and willingness to compromise) to .66 (desire to please others). The median T1-T2 correlation was .57.
Validity of the CDMP model
  • Exploratory factor analysis supported the structure of the theoretical model and questionnaire;
  • Confirmatory factor analysis with a sixth Hebrew sample (N=431) supported the structure of 11 separate dimensions (with 3 items for each dimension), which cannot be combined into a single aggregate factor.
  • Confirmatory factor analysis of the English version (N=208) also supported the multidimensional structure of the CDMP.
