• People with a strong external locus of control tend to praise or blame external factors

3

Introduction

• Wallston et al. (Health Locus of Control)

• Internal

• Powerful Other

• Chance

Aim

• To Study relation between Health Locus of Control (HLC) with Health Promoting Behaviors (HPB) of people over 15 years old in Bandar Abbas, Iran.

5

Methods

• Population based study

• Population study: people over 15 years old

• Be able to answer the items

• To omit cluster sampling effect: +10%

• 38 cluster from different areas of the city

• In each cluster 22 individual

• Totally: 836

7

Data Collection

• Forms: A, B, C

• In This Study: Form A

• Form A:

• Internal

• Chance

• Powerful Other

8

Data Collection

• Form A including 18 items: Likert 1(strongly disagree)

to 6 (Strongly Agree)

• Internal: Six items, 6-36

• Chance: Six items, 6-36

• Powerful Other, Six Items, 6-36

Data Collection• Health Promoting Behaviors was assessed by Health

Promoting Lifestyle Profile II• This scale has 52 items: Likert: 1-5 • Six subscales including:• Social Support• Spiritual Growth• Health Responsibility• Stress Management• Nutrition Behaviors• Physical Activity

Discussion

• As the result showed there was direct correlation between

age with internal health locus of control and powerful

other.

• In Grotz et al. study in Germany there was direct

correlation between age with powerful other and chance.

• In Kuwahara et al. study in Japan there was direct

correlation between age with all subscales of HLC.

24

Discussion

• As the results showed Internal health locus of control and powerful

other predict HPB.

• Studies have shown that people with Internal health locus of control,

more intend to take behaviors that can prevent disease and promote

their health.

• In Grotz et al. study, people with high scores in chance had less

physical activity.

• In Norman et al. study, people with high scores in internal health

locus of control had more physical activity and better nutritional

behaviors.

25

Conclusion

• HLC of Studied people is more internal followed by

powerful other and is less by chance.

• Internal health locus of control and powerful other predict

HPB.

• To increase knowledge of people regarding determinants

of health and empower of them in order to promote

internal health locus of control and finally improve HPB is

recommended.
