Abstract

Background

Supervised exercise interventions produce the largest improvements in patient-reported outcomes in cancer survivors but their scalability has been questioned. Telephone counseling has been proposed as a more feasible alternative but its impact on exercise behavior and health outcomes have been modest. Basing telephone counseling exercise (TCE) interventions on the theoretical advances described in the multi-process action control framework (M-PAC) may improve these outcomes.

Purpose

To assess the feasibility and preliminary efficacy of a M-PAC-based TCE intervention for increasing aerobic exercise behavior in hematologic cancer survivors (HCS).

Methods

We recruited 51 HCS who were randomized to either a weekly TCE group (n = 26) or a self-directed exercise (SDE) group (n = 25). Participants completed online measures of self-reported aerobic exercise behavior, quality of life (QoL), fatigue, and program satisfaction at baseline and post-intervention (12 weeks).

Results

Adherence to the TCE intervention was 93% and retention was 100%. Participants receiving TCE increased their weekly aerobic exercise by 218 min compared to 93 min in the SDE group [mean-adjusted between-group difference (MBGDadj) = 139, 95%CI = 65 to 213, p < .001, effect size (d) = 2.19]. Clinically meaningful QoL improvements favored the TCE group for mental health (MBGDadj = 3.7, 95%CI = − 0.4 to 7.9, p = .08, d = 0.42) and mental health component (MBGDadj = 3.6, 95%CI = − 0.8 to 8.1, p = .10, d = 0.35) subscales.

Conclusions

The 12-week TCE intervention substantially increased exercise behavior and may have meaningfully improved QoL in HCS.

Implications for Cancer Survivors

Though more definitive trials are needed, remote TCE interventions based on the M-PAC may improve exercise behavior and QoL in HCS and perhaps other cancer survivor groups.
