Abstract:Background: Pain is a common and annoying phenomenon. In the Netherlands, one in five suffer from chronic pain. Chronic pain is associated with serious consequences and obstacles to personal and social life, so the quality of life deteriorates. The pain patients receive no specific pain treatments and have inadequate control of pain. They are constantly working to reduce and avoidance pain instead of living the life by their values, which they aspire. Values are motivational constructs that involve the beliefs that people hold about desirable goals that can be applied across contexts and time. Acceptance and Commitment Therapy (ACT) has proven effective in treating chronic pain, the effects are mainly determined by the concepts ‘acceptance of pain’ and ‘value-oriented actions’. Values related to processes enhance the performance, so it does not relate to pain anymore. Therefore, it is important to measure values-directed to life. The Chronic Pain Values Inventory (CPVI) and the Valued Living Questionnaire (VLQ) are qualitative value-directed life measurements devices from the ACT. However, there are no quantifiable questionnaires for empirical research that measures the values-oriented life in chronic pain patients. The Twente Values Scale (TVS) developed by the Department of Psychology, Health and Technology at the University of Twente, from the context of ACT, to measure 'value-oriented life'. Purpose: The purpose of this thesis is to examine the psychometric properties of the TVS in the chronic pain population. Methods: The psychometric properties of the TVS are examined by factor structure, reliability and validity of the TVS. For validity of the TVS were also the questionnaires HADS, MDI-DLV and PIPS decreased. The sample consisted of 238 chronic pain patients. Results: An Exploratory Factor Analysis (EFA), with the Maximum Likelihood (ML) method, validated a two-factor structure which revealed 39.7% of the variance. The Cronbach's Alpha for the subscales ‘Motivated evaluative life’ and ‘Awareness of values’ and the total scale of the TVS was respectively .89, .86 and .91. The correlations of the TVS with HADS, MDI-DLV and PIPS were respectively r = - .44, r = - .35 and r = - .44 (p <0.01). Discussion: The TVS seems to be a valid instrument with reasonably to good psychometric qualities and suitable for use as an empirical 'value-oriented life' measurement. The long term effects are still unknown, it is recommended to be further investigated.
