Studies have indicated that chronic low back pain (LBP) should be approached according to its morphological basis and in consideration of biopsychosocial interventions. This study presents an updated review on available psychological assessments and interventions for patients with chronic LBP. Psychosocial factors, including fear-avoidance behavior, low mood/withdrawal, expectation of passive treatment, and negative pain beliefs, are known as risk factors for the development of chronic LBP. The Örebro Musculoskeletal Pain Questionnaire, STarT Back Screening Tool, and Brief Scale for Psychiatric Problems in Orthopaedic Patients have been used as screening tools to assess the development of chronicity or identify possible psychiatric problems. The Pain Catastrophizing Scale, Pain Self-Efficacy Questionnaire, and Injustice Experience Questionnaire are also widely used to assess psychosocial factors in patients with chronic pain. With regard to interventions, the placebo effect can be enhanced by preferable patient-clinician relationship. Reassurance to patients with non-specific pain is advised by many guidelines. Cognitive behavioral therapy focuses on restructuring the negative cognition of the patient into realistic appraisal. Mindfulness may help improve pain acceptance. Self-management strategies with appropriate goal setting and pacing theory have proved to improve long-term pain-related outcomes in patients with chronic pain.
