Interpersonal problem behavior and low back pain.

OBJECTIVE: The theory of interpersonal problem behaviour (IPB) provides a more fundamental framework for understanding the psychosocial aspects of pain. The present study focused on the IPB, based on the Interpersonal Problem Circumplex (IPC), in persons with low back pain and its association with pain, psychological characteristics, and health care utilisation. METHODS: In a cross-sectional design, individuals with back pain (N = 88) and healthy control persons who matched by age, gender, and educational level (N = 88) were compared with regard to IPB. Furthermore, back pain patients classified by their IPB (N = 24 low, N = 48 moderate, N = 16 high) were compared regarding pain, depression, catastrophising, and health care utilisation. RESULTS: In comparison to the healthy reference sample, a significant difference in the interpersonal problems of the low back pain group, with a tendency towards being overly 'introverted', 'exploitable', and 'subassertive', was revealed. In the back pain group, participants with elevated IPB showed significantly higher levels of pain intensity, functional disability, depression, catastrophising, and health care utilisation than participants with IPB in the normal range. CONCLUSION: Application of the Interpersonal Circumplex Model can help to characterize a subgroup of persons with low back pain. Increased general interpersonal problems are associated with elevated burden in pain-related, psychological, and health care-related variables. Future research should focus on the treatment opportunities for this subgroup, as well as on the influence of interpersonal problems during the course of back pain.

Effectiveness of a Multimodal Therapy for Patients with Chronic Low Back Pain Regarding Pre-Admission Healthcare Utilization.

OBJECTIVE: The aim of the study was to examine the effectiveness of an intensive inpatient three-week multimodal therapy. We focused especially on the impact on the multimodal therapy outcome of the pre-admission number of treatment types patients had received and of medical specialist groups patients had consulted. METHODS: 155 patients with chronic low back pain and indication for multimodal therapy were evaluated with respect to pain intensity, depression, anxiety, well-being, and pre-admission health care utilization. In our controlled clinical trial we compared N = 66 patients on the waiting list with N = 89 patients who received immediate treatment. The waiting list patients likewise attended multimodal therapy after the waiting period. Longitudinal post-treatment data for both were collected at three- and twelve-month follow-ups. The impact of pre-admission health care utilization on multimodal therapy outcome (post) was analysed by structural equation model. RESULTS: Compared to the control group, multimodal therapy patients' pain intensity and psychological variables were significantly reduced. Longitudinal effects with respect to pre-measures were significant at three-month follow-up for pain intensity (ES = -0.48), well-being (ES = 0.78), anxiety (ES = -0.33), and depression (ES = -0.30). Effect sizes at twelve-month follow-up were small for anxiety (ES = -0.22), and moderate for general well-being (ES = 0.61). Structural equation model revealed that a higher number of pre-admission treatment types was associated with poorer post-treatment outcomes in pain intensity, well-being, and depression. CONCLUSION: Multimodal therapy proved to be effective with regard to improvements in pain intensity, depression, anxiety, and well-being. The association between treatment effect and number of pre-admission pain treatment types suggests that patients would benefit more from attending multimodal therapy in an earlier stage of health care.

[Health care system utilization due to low back pain: sociodemographic, pain-related and psychosocial determinants]. / Inanspruchnahme medizinischer Versorgung bei Rückenschmerzen: soziodemografische, schmerzbezogene und psychosoziale Determinanten.

UNLABELLED: The study's aim was to identify associations between socio-demographic, psychosocial and pain-related factors and health care utilization due to low back pain.In this cross-sectional Survey 372 hotel employees completed standardized questionnaires to examine pain characteristics, psychosocial (working) conditions and health care use in the previous 12 months. Data was analyzed using binary logistic regression. All together 79.8% of the subjects reported low back pain in the previous 12 months and slightly more then half of them were seeking care. Significant predictors for health care use were physical functioning, frequency of pain (periodic vs. permanent) and pain-related coping. CONCLUSIONS: Sufferer of low back pain without consultation had significant less pain-related functional disability and tended less to mal-adaptive Coping. Work satisfaction and endurance-strategies were not associated to health care use.
