The current research examined the proposition that individuals who were securely attached had a fundamentally different reaction and experience of chronic pain to the experience of individuals with an insecure attachment style. A biopsychosocial model of chronic pain was created that included the variables of attachment style, pain, depression, anxiety, somatisation, quality of life, function, disability, neuroticism, age and gender. Three cross-sectional quantitative studies and one qualitative study were conducted. Participants were (a) patients from a multidisciplinary pain centre in a major public hospital, and (b) members of the general population with chronic pain who were recruited from both urban and rural settings, across various community support groups. The total sample was 470. Instruments for the quantitative studies included the Revised Adult Attachment Scale (Collins & Read, 1990), the McGill Pain Questionnaire (Melzack, 1975), the Pain Patient Profile (Tollinson & Langley, 1992), the Quality of Life Inventory (Frisch, 1994), the International Association for the Study of Pain Assessment Protocol (International Association for the Study of Pain, 1986), the Migraine Disability Scale (Stewart, Lipton, Kolodner, Liebermann, & Sawyer, 1999), and the short form of the Eysenck Neuroticism Scale (Eysenck, Eysenck, & Barret, 1985). The clinical and non-clinical participants with a diagnosis of chronic pain syndrome were partitioned as securely or insecurely attached. In the clinical sample, the proportion of securely attached individuals was less than one quarter of the group, while in the non-clinical sample the proportion of individuals in the securely attached group was 50%. For Study 1, (200 individuals from the clinical sample), the groups were partitioned using the classification criteria of Collins and Read (1990). Securely attached participants = 27%, insecurely attached 73%. An analysis of effect of attachment style on overall pain showed that the Securely Attached group reported less overall pain than the Insecurely Attached group. For Study 2, (using the total clinical sample), the sample comprised 27.3% securely attached and 72.7% insecurely attached participants. The Securely Attached group reported less overall Pain, less Negative Affect and Somatisation than the Insecurely Attached group, and higher levels of Quality of Life. Somatisation provided a significant unique contribution of variance to predicting overall Pain, providing some support for the biopsychosocial model, and Negative Affect (Depression and Anxiety combined) made a significant unique contribution to Quality of Life, explaining 26% of the variance. Gender was unrelated to any variable. For Study 3, the sample consisted of rural and urban participants, and the rural group was significantly older than the urban group. No other differences were found. The groups were combined to form the non-clinical group. The group was evenly divided (50%) between securely and insecurely attached groups. Gender was unrelated to any variable. For the non-clinical group, using the variables investigated in Study 2, there was no difference on overall pain scores, but negative affect and somatisation were higher and quality of life lower in the insecure group than in the secure group. No differences were found on Pain Intensity but Pain Pattern differed between the groups. Three new variables were added to the model - Neuroticism, Function and Disability. Disability and Function were significantly different between the attachment style groups. Age was significantly related to lower pain scores, less loss of function, less disability and higher quality of life. Pain scores were most related to somatisation, with age and quality of life contributing significant variance. Neuroticism added further to this explanation. Negative Affect made the most contribution to the variance explained in quality of life, and neuroticism and function made no significant contribution. Neuroticism and Attachment Style contributed significant amounts of variance to Function. To compare the Secure and Insecure Attachment groups in the Clinical and Non-clinical samples, a matched groups study, N = 190, was conducted. Clinical and non-clinical participants were matched for Age, Gender and Attachment Style. No differences were reported on overall pain between the attachment groups, but differences existed on negative affect, somatisation and quality of life. For sample type, the clinical group reported higher overall pain scores, less negative affect and less somatisation, but no differences were found on quality of life, compared to the non-clinical group. Study 4 was a qualitative study that used structured interviews of 24 clinical and non-clinical participants matched for age, gender, attachment style and etiology. The securely attached group reported having extensive, positive social support, high community involvement and appropriate reliance on medical and allied health care and medications. The insecurely attached group reported more problems with physical pain and psychological distress, less social support, less function and more perceived disability. The insecurely attached group reported more use of medical, allied and alternative health resources. Older securely attached individuals reported the lowest overall pain scores and the highest quality of life. These results support the hypotheses that a secure attachment style contributes to more positive outcomes for individuals with chronic pain syndrome and were consistent with a model of chronic pain that includes biological, psychological and social variables.
