ObjectiveThe problem of boredom in people with cancer has received little research attention, and yet clinical experience suggests that it has the potential to profoundly affect quality of life in those patients. We were interested in developing a Purposelessness, Understimulation, and Boredom (PUB) Scale to identify this problem and to begin to differentiate it from depression.MethodsCancer patients and professionals were interviewed using a semi-structured format to elicit their perceptions of the incidence, causes, scope, and consequences of boredom. From their responses, 45 questions were developed, edited for clarity, and piloted. A total of 100 cancer patients were recruited to participate in the study. Preliminary validation of the PUB using a cross-sectional survey of the measure was conducted. Other instruments used for purposes of convergent and divergent validity included the Functional Assessment of Cancer Therapy Scale-Anemia, Zung Self-Rating Depression Scale, Boredom Proneness Scale, Leisure Boredom Scale, Cancer Behavior Inventory, Systems of Belief Inventory, and the Eastern Cooperative Oncology Group Performance Status Scale.ResultsThe average age of the sample was 62.37 years (SD = 13.43) and was comprised of 60 women (60.00%) and 40 men (40.00%). The results of a factor analysis on the 45 initial items (selected on the basis of professional and patient interviews) created a two-factor scale. The eight items from the strongest factor (items 1, 2, 3, 4, 5, 6, 9, 10) seemed to best tap the construct that could be deemed as overt boredom whereas the six items of the second factor (items 36, 38, 39, 42, 44, 45) seemed to tap the construct of boredom related to meaning and spirituality. Total scale internal consistency, when all 14 items were included in the analysis, yielded a coefficient alpha of 0.84 and good test-retest reliability at 2 weeks (r = .80, p < .001). The novel 14-item PUB Scale was significantly correlated to other measures of boredom; the Boredom Proneness Scale (r = -.588, p < .001) and the Leisure Boredom Scale (r = .576, p < .001).Significance Of ResultsThe PUB Scale was found to be a statistically viable tool with the ability to detect boredom and differentiate it from depression. In many respects this work is in concert with much of the current research and clinical effort going on in psycho-oncology that defines components of distress that in sum, redefines depression in advanced cancer.
