  2. Change from baseline self-report 'quality of life' at end of 8-session psychological intervention (approximately 8 weeks) and at post-therapy eight week follow-up (using the Work and Social Adjustment Scale) [ Time Frame: Measure taken at first therapy appointment (baseline), taken again after 8-session intervention (approximately 8 weeks) and again at eight week post-therapy follow-up ]
    The Work and Social Adjustment Scale (Mundt, Marks, Shear, & Greist, 2002) is a 5-item self-report questionnaire measuring functional impairment and disability attributable to the effects of a health condition using a 9-point likert scale
