The main purpose of this study is to examine the contribution of personality traits to marital satisfaction and well -being among couples coping with Coronary Heart Disease (CHD) and couples from the general population, and to health promoting behaviors and physical recovery among the ill partners.

Heart disease is the world's leading cause of death in most industrial countries and it requires drastic changes in the lifestyle of the patient. Research on social support and coping with stress has repeatedly shown that being in a supportive spousal relationship has a significant effect on the recovery from a heart disease through alterations in mood, as well as through health habits. However, there are interpersonal differences in the abilities to receive and to provide support. Most of the literature to date has focused either on the experiences of the support recipient or on the support provider; much less research has taken both partners' characteristics into consideration (Revenson & DeLongis, 2011).

The current research aims to broaden the understanding of spousal support among couples coping with a life threatening illness- Coronary Heart Disease (CHD) versus general population of couples. Two studies were designed. Study 1(control group) will focus on general population of couples and its goal is examine the contribution of personality traits of the couples to their marital satisfaction and well-being. Study 2 (target group) will focus on couples coping with a first acute coronary heart disease and its goal is to examine the contribution of personality traits of the couples to their marital satisfaction and well-being, and to health promoting behaviors (smoking cessation, medication adherence) and physical recovery (change in body mass index, change in cholesterol levels) of the ill partners.

The proposed research is a prospective, longitudinal study. The control group will be 100 couples who are not coping with a life threatening illness. The couples will complete self report questionnaires. The target group will be 127 male patients and their partners. The couples will be recruited during the patients' first hospitalization for ACS. The participants will complete questionnaires during the hospitalization and again six months later. Relevant data will be obtained from their medical files.

This study's findings could inform clinicians whose goal is to foster better patient-spouse dynamics in the context of major medical stressors. Helping couples master the challenge of providing and receiving support in such trying times may contribute to enhanced levels of adherence among patients which, in turn, would lead to improved health and saved lives.
