Data analyses were performed using the SPSS 22.0 software, and AMOS 20.0 statistics packages. The age range of participants was 23 - 47 (31.07 ± 4.37 years). The mean age for men was 32.89 years (SD = 4.25) and for women was 30.05 years (SD = 4.11). In the case of the distribution of the educational level, 13% of the participants had PhD, 50% had MA/MSc, and 37% had BA. Since d
2 values were not distinctively apart (
24), the multivariate outliers were not a problem. The critical ratio of 2.05 for Mardia’s coefficient (4.27) proved the multivariate normality (
25). The model was therefore tested using maximum likelihood (ML) estimation and bootstrap procedure (to assess mediation through examining the specific indirect effects within the model, (
26) in AMOS.20).
Table 1 shows the descriptive statistics, and the matrix of the relationships among the model variables, respectively.
As shown in
Table 1, there were significant internal correlations among all variables of the model. The correlation coefficient between dyadic adjustment scales (dyadic consensus, dyadic satisfaction, and dyadic cohesion) and existential well-being (r = 0.58, 0.51 and 0.44, respectively) were higher compared to the correlations between each of them and religious well-being (r = 0.31, 0.22 and 0.21, respectively). The correlation coefficients between both dyadic consensus and dyadic satisfaction and communication/conflict resolution (r = 0.69, and 0.60, respectively) were higher than the correlation coefficients of these scales and other family strengths. The correlation coefficient between dyadic cohesion and time spent together (r = 0.52) was higher than the correlation coefficient of this scale and other family strengths. The correlation coefficients between both dyadic consensus and dyadic cohesion and commitment to stability (r = 0.32 and 0.18, respectively) were lower than the correlation coefficients of these scales and other family strengths. The correlation coefficient between dyadic satisfaction and commitment to growth (r = 0.30) was lower than the correlation coefficient of this scale and other family strengths.
Figure 1 shows standardized direct effect coefficients for the relationships among model variables.
Results showed that the standardized direct effects of spiritual well-being on positive interaction/appreciation (0.13, P = 0.09), personal worth of self and others on commitment to stability (0.02, P = 0.11) and dyadic adjustment (0.09, P = 0.15), commitment to stability on commitment to growth (0.03, P = 0.13), positive interaction/appreciation (0.03, P = 0.18), time together (0.08, P = 0.10) and dyadic adjustment (.06, P = 0.20), commitment to growth on positive interaction/appreciation (0.04, P = 0.13), time together (0.04, P = 0.15) and dyadic adjustment (0.09, P = 0.06), were not significant. As shown in
Figure 1, spiritual well-being has a direct effect on personal worth of self and others (0.69, P < 0.01), commitment to stability (0.42, P < 0.01), commitment to growth (0.28, P < 0.01), communication/conflict resolution (0.20, p < 0.01), time together (0.20, P < 0.01) and dyadic adjustment (0.24, P < 0.01). Personal worth of self and others had a direct effect on commitment to growth (0.33, P < 0.01), communication/conflict resolution (0.41, P < 0.01), positive interaction/appreciation (0.38, P < 0.01) and time together (0.21, P < 0.01). Commitment to stability and commitment to growth had a direct effect on communication/conflict resolution (0.15 and 0.18, P < 0.01, respectively). Communication/conflict resolution had a direct effect on positive interaction/appreciation (0.39, P < 0.01), time together (0.23, P < 0.01) and dyadic adjustment (0.34, P < 0.01). Positive interaction/appreciation had a direct effect on time spent together (0.16, P < 0.01) and dyadic adjustment (0.25, P < 0.01). Time spent together had a direct effect on dyadic adjustment (0.27, P < 0.01).
As shown in
Table 2, spiritual well-being has indirect effects on commitment to growth through the mediating role of personal worth of self and others (0.23, CI [0.11, 0.36; P = 0.003], standardized total effect = 0.51), communication/conflict resolution through mediating roles of personal worth of self and others, commitment to stability, and commitment to growth (0.43, CI [0.33, 0.54; P = 0.002], standardized total effect = 0.63), positive interaction/appreciation through the mediating roles of personal worth of self and others, commitment to stability, commitment to growth, and communication/conflict resolution (0.51, CI [0.41, 0.59; P = .005], standardized total effect = 0.51), time spent together through the mediating roles of personal worth of self and others, commitment to stability, commitment to growth, communication/conflict resolution, and positive interaction/appreciation (0.38, CI [0.28, 0.49; P = 0.003], standardized total effect = 0.58), and dyadic adjustment through the mediating roles of personal worth of self and others, commitment to stability, commitment to growth, communication/conflict resolution, positive interaction/appreciation, and time spent together (0.50, CI [0.41, 0.63; P = .003], standardized total effect = 0.74). The results showed that personal worth of self and others had no effect on commitment to stability but had an indirect effect on communication/conflict resolution through the mediating role of commitment to growth (0.06, CI [0.02, 0.13; P = 0.003], standardized total effect = 0.47), positive interaction/appreciation through mediating roles of commitment to growth and communication/conflict resolution (0.18, CI [0.11, 0.29; P = .002], standardized total effect = 0.56), time spent together through the mediating roles of commitment to growth, communication/conflict resolution, and positive interaction/appreciation (0.20, CI [0.11, 0.32; P = 0.003], standardized total effect = 0.41), and dyadic adjustment through the mediating roles of commitment to growth, communication/conflict resolution, positive interaction/appreciation, and time spent together (0.41, CI [0.29, 0.51; P = .003], standardized total effect = 0.41). Commitment to stability had an indirect effect on positive interaction/appreciation through the mediating role of communication/conflict resolution (0.06, CI [0.02, 0.10; P = 0.003], standardized total effect = 0.06), time spent together through mediating roles of communication/conflict resolution and positive interaction/appreciation (0.04, CI [0.01, 0.09; P = 0.003], standardized total effect = 0.04), and dyadic adjustment through the mediating roles of communication/conflict resolution, positive interaction/appreciation, and time spent together (0.08, CI [0.03, 0.13; P = .004], standardized total effect = 0.08). Commitment to growth had an indirect effect on positive interaction/appreciation through the mediating role of communication/conflict resolution (0.07, CI [0.02, 0.12; P = 0.007], standardized total effect = 0.07), time spent together through the mediating roles of communication/conflict resolution and positive interaction/appreciation (0.05, CI [0.02, 0.11; P = 0.004], standardized total effect = 0.05), and dyadic adjustment through the mediating roles of communication/conflict resolution, positive interaction/appreciation and time spent together (0.09, CI [0.03, 0.16; P = 0.005], standardized total effect = 0.09). Communication/conflict resolution had an indirect effect on time spent together through the mediating role of positive interaction/appreciation (0.07, CI [0.02, 0.12; P = 0.004], standardized total effect = 0.30), and dyadic adjustment through the mediating roles of positive interaction/appreciation and time spent together (0.18, CI [0.11, 0.26; P = 0.003], standardized total effect = 0.52). Positive interaction/appreciation had an indirect effect on dyadic adjustment through the mediating role of time spent together (0.04, CI [0.02, 0.09; P = 0.003], standardized total effect = 0.29). The conceptual model explained 23% of the distribution of dyadic adjustment.
