Daily Marital Tension and Symptom Severity in Older Adults With Diabetes or Osteoarthritis.

Background: Greater marital quality is associated with better psychological and physical health. The quality of daily marital interactions is likely to be especially important for individuals with chronic illness, but this question has received little attention.

Purpose: Using data from two diary studies, the current study examined whether individuals with chronic illness would experience more severe symptoms on days with more marital tension due in part to greater negative affect on those days.

Spouse confidence and physical function among adults with osteoarthritis: The mediating role of spouse responses to pain.

Objective: This study of adults with osteoarthritis and their spouses examined spouse responses to patients' pain as mediators of the associations between spouse confidence in patients' ability to manage arthritis and improvements in patients' physical function and activity levels over time.

Method: Participants were 152 older adults with knee osteoarthritis and their spouses. In-person interviews were conducted with patients and spouses (separately) at 3 time points: baseline (Time[T] 1), 6 months after baseline (T2), and 18 months after baseline (T3).

Effects of change in arthritis severity on spouse well-being: The moderating role of relationship closeness.

The severity of a patient's illness may be detrimental for the psychological well-being of the spouse, especially for those in a particularly close relationship. Using 2 waves of data collected from a sample of 152 knee osteoarthritis (OA) patients and their spouses, we examined associations between change in patients' illness severity and change in 3 indicators of spouses' well-being (positive affect, depressive symptoms, and life satisfaction) over a 6-month period. We also tested the hypothesis that spouses' perceived relationship closeness with the patient would moderate these associations.

Spouses' attempts to regulate day-to-day dietary adherence among patients with type 2 diabetes.

Objective: To investigate daily dietary adherence and diabetes-specific distress among older adults with type 2 diabetes mellitus (T2DM) as a function of spouses' diet-related support and diet-related control (persuasion and pressure) and whether these daily processes differ among couples who do and do not appraise responsibility for managing T2DM as shared.

Methods: End-of-day diaries were completed by 126 couples in which one partner had T2DM (patient) and the other did not (spouse). Using electronic diary methods, each partner independently recorded data for 24 consecutive days (patients recorded their day's dietary adherence and diabetes-specific distress; spouses recorded their day's involvement in patients' dietary management).

Older adults' beliefs about the timeline of type 2 diabetes and adherence to dietary regimens.

The common-sense model posits that behavioural coping with illness is shaped by a complex combination of individuals' abstract and concrete beliefs about their illness. We investigated this theoretical assumption in a study of 116 older adults diagnosed with type 2 diabetes who completed in-person interviews at baseline and six and 12 months later. Specifically, we examined (1) the interaction of patients' abstract and concrete beliefs about the timeline of their diabetes as a predictor of change in adherence to a healthy diet and (2) whether these interactive effects differ among male and female patients.

Setbacks in diet adherence and emotional distress: a study of older patients with type 2 diabetes and their spouses.

Objectives: We investigated patients' difficulties in managing their diet (i.e. diet setbacks) and associations with change in disease-specific and general emotional distress (diabetes distress and depressive symptoms) among patients with type 2 diabetes and their spouses.
