Empirical data regarding a network of psychosocial determinants for two treatment goals. Structural equation model: rectangles indicate observed indicator variables. The highest-positioned rectangle received a fixed regression weight of 1. Ovals indicate unobserved latent variables. Numbers at single-headed arrows indicate standardized regression weights (bold indicates β-values with P < 0.05). Numbers at variables indicate squared multiple correlation coefficients. There were no indefinite matrixes and no constrained parameters. The SEM of standardized regression weights was <0.149 (χ2 = 88.5, df = 76, P = 0.16). Fit indexes: Cmin/df = 1.16, AGFI = 0.94, goodness of fit index = 0.96, RMSEA = 0.02, Tucker-Lewis index (Bentler and Bonnett non-formed fit index) = 0.99. The standardized regression weights between age and the observed variables were as follows: coping, knowledge −0.42 (P = 0.004); active behavior 0.06 (P = 0.117). Quality of life; physical −0.20 (P = 0.004), psychological 0.07 (P = 0.020). Patient, self-efficacy 0.08 (P = 0.034), optimism 0.07 (P = 0.045). Doctor-patient relationship: competence 0.06 (P = 0.032), empathy 0.15 (P = 0.004). Illness: secondary illnesses 0.30 (P = 0.004).
