This research focused on constructing a psychological profile for change interventions by investigating both the interrelationships and overall relationships between work stress (as the independent variable), psychological attachment (job embeddedness and organisational commitment) (as the mediating variables) and attitudes towards change (as the dependent variable). A non-experimental cross-sectional quantitative survey design approach using standardised valid and reliable measuring instruments (Sources of Job Stress Scale, Organisational Commitment Questionnaire, Job Embededdness Questionnaire, Attitudes towards Change Questionnaire) was used on a non-probability purposive sample of employees from one of the largest, fast-moving consumer goods companies in South Africa (N = 350), ranging from administrative to executive level. Bivariate correlations showed a statistically positive inter-relationship between sources of work stress, psychological attachment (job embeddedness and organisational commitment) and attitudes towards change. A canonical correlation analysis indicated a significant overall relationship between the sources of work stress, psychological attachment (job embeddedness and organisational commitment) and attitudes towards change dispositions. Mediation modelling revealed the mediating role of psychological attachment (organisational commitment and job embeddedness) in the sources of work stress and attitudes towards change relationship. Moderated hierarchical regression analyses showed that age and gender significantly moderated the relationship between individuals’ sources of work stress and their attitudes towards change dispositions. Tests for mean differences revealed that significant differences exist between age and sources of work stress, affective and continuance commitment, fit and sacrifice embeddedness. Differences exist between race groups’ affective and continuance commitment. Job security is a concern across all employment levels in the organisation. Individuals at an executive, upper administrative and administrative level revealed significant differences in terms of their continuance commitment. Cognitive and behavioural attitudes towards change did not differ significantly across all employment levels. At a theoretical level, this study developed an understanding of the cognitive, affective, conative and interpersonal behavioural dimensions of the hypothesised psychological profile to manage change. At an empirical level, it developed an empirically tested psychological profile for change interventions in terms of the various behavioural dimensions. At a practical level, organisational change practices in terms of the behavioural dimensions of the psychological profile were recommended. / Psychology / D. Phil. (Psychology)
