Positive Psychological Interventions for Patients with Type 2 Diabetes: Rationale, Theoretical Model, and Intervention Development

In the paper

“Overall, the mean age of participants was 60.1 ± 8.8 years, 9 (60%) were women, and the majority had one or more additional cardiovascular risk factors (e.g., hypertension and hyperlipidemia).”

In the paper

“Most participants were moderately nonadherent, with a mean MOS SAS score of 11.4 out of 18, consistent with a mean rating of 3.8 out of 6 for completion of each health behavior (diet, activity, and medication adherence).”

In the paper

“There were no differences in the age (t = 0.35; P = 0.71), race (χ 2 = 1.86; P = 0.17), or gender (χ 2 = 0.47; P = 0.49) of participants who declined participation compared to those who enrolled; additional data on decliners was not collected.”

In the paper

“In total, during time periods when study staff were available for recruitment for this unfunded feasibility trial, 69 patients with T2D were identified, 44 were judged by clinicians to be potentially eligible, 29 agreed to hear about the study, and 15 were eligible and enrolled.”

In the paper

“Overall, the mean age of participants was 60.1 ± 8.8 years, 9 (60%) were women, and the majority had one or more additional cardiovascular risk factors (e.g., hypertension and hyperlipidemia).”

In the paper

“Thus far nine participants have completed the study, with six participants still undergoing study procedures; of the nine initial participants, seven (78%) fully completed at least three PP exercises.”

In the paper

“In T2D, positive psychological states (e.g., positive affect, well-being) are prospectively associated with lower HbA1c, fewer diabetes complications, and lower rates of cardiac events/mortality [26–28]”

In the paper

“A novel health behavior intervention that combines MI and PP in T2D may be very effective.”

In the paper

“As described, another potential use is that PP could be combined with other behavioral interventions (e.g., MI) to boost engagement and adherence with little added burden.”

In the paper

“This combination of a psychological component (that can boost optimism, confidence, and positive experiences) alongside a more tightly focused, goal-oriented, and cognitive MI component may be much more powerful in this complex and vulnerable population than either approach alone.”

In the paper

“However, we have just begun to test PP interventions in patients with T2D and suboptimal health behavior adherence, and it is likely that additional customization of the intervention more specifically to T2D will be useful.”

In the paper

“Prior attempts to combine health behavior interventions with psychological interventions have been successful in T2D but thus far have been designed only for minority of patients with clinical depression [152].”

In the paper

“Limitations of our specific proof-of-concept trial also include the use of only a single inpatient and a single outpatient site in an academic medical center and the fact that the majority of participants were white; these factors may limit generalizability of findings.”

In the paper

“Overall, this line of work is still in very early stages and PP interventions (alone or combined) are far from established health-promoting interventions.”

In the paper

“In addition, PP interventions appear to reliably increase these positive states, have been well accepted in other populations, and are distinct from other behavioral interventions in their ease of administration, high acceptability, and specific focus on promoting positive psychological well-being.”
