Differences in Mechanistic Measures (Oxytocin and Cortisol) of Therapeutic Alliance Between A Talk-Based Therapy and Soft-Tissue Mobilization in Individuals With Chronic Spinal Pain

The goal of this randomized cross-over mechanistic trial is to compare pre- and post-level cortisol and oxytocin changes in patients with chronic spine pain who receive either a hand's on (massage) or a hand's off (talk-based) approach. The study plans to address two primary aims. Specific Aim One: Directly compare pre- and post-session oxytocin and cortisol levels across two sessions of massage and talk-based therapy. Hypothesis 1: It is expected that in both treatments, oxytocin will increase and cortisol will decrease, demonstrating no significant between-group differences in hormone levels. Specific Aim Two: The study plans to compare pre- and post-session oxytocin and cortisol change scores a therapeutic alliance (TA) scale change scores and PROMIS patient-reported outcomes associated with pain, depression, and disability. Hypothesis 2a: It is projected that there will be moderate +/- relationships (R\>.4) between the therapeutic alliance change score and oxytocin and cortisol levels, suggesting that the hormones moderately reflect the construct associated with TA. Hypothesis 2b: It is expected that there will be weak (R\>.1) +/-relationships between hormone measures and PROMIS pain/disability/depression measures, which reflects similar findings to preliminary work. Participants will participant in a massage based treatment and a talk-based treatment approach. Participants will also complete patient report outcomes and will receive a total of four salivary swabs.
