Personality and health protective behavior. Eur J Pers 1999;13: Stress and coping strategy influence on health behaviors Sense of coherence and social support are positively associated with health behaviors However, few studies have investigated the influence of personality, stress, coping methods, sense of coherence, and social support on a healthy diet.

4 Objective To determine the relationship between self-perception of diet quality and related factors: Personality Impulsiveness Stress Coping strategy Sense of coherence Self-efficacy social support.

5 Methods : design and sample Cross-sectional study (October 2009) Face to face interview after multiple-stratified random sampling from a population-based database 1,530 participants aged 30 or older who did not have a history of cancer (response rate 36%)

6 Methods : measures Self-perception of diet quality : to indicate if they consumed a diverse, well-balanced diet that included sufficient amounts of fruits and vegetables Personality : Ten-Item Personality Inventory developed by Gosling (2003). Big Five personality domains (extraversion, agreeableness, conscientiousness, emotional stability, and openness to experience) Impulsiveness : Barratt Impulsiveness Scale (1997) Stress : Psychosocial Well-being Index-short form (PWI-SF) (2000)

7 Methods : measures Coping strategy : Coping Strategy Indicator developed by Amirkhan (1990) Sense of coherence : Sense of Coherence Scale (SOC-13) developed by Antonovsky (1993) Self-efficacy : to indicate if they were capable of consuming a diverse, balanced diet with sufficient fruits and vegetables Social support : Multidimensional Scale of Perceived Social Support (MSPSS) developed by Zimet (1988)

10 Discussion Optimistic perception of their diet : 63.1% (perception) vs 25.7% (objective proportion, Ministry of Health & Welfare, 2008) Stress management program will be helpful People who resist the negative effects of stress are more likely to consume healthy diet Self-efficacy has been used to assess dietary behavior and is generally accepted as a significant indicator It is necessary to determine which social support sources provide certain types of support, because this can guide efforts to promote healthy diet based on the receivers educational needs

11 Limitation The measure of diet variable and self-efficacy were limited to a single question Actual frequency and volume of the consumption of fruits and vegetables is needed
