The Diet Self-Efficacy Scale (DIET-SE)

Scale name: The Diet Self Efficacy Scale (DIET-SE)

Scale overview: The Diet Self-Efficacy Scale (DIET-SE) is an 11-item self-report measure. Respondents rate their degree of confidence in managing eating situations.

Authors: Stich et al. (see reference below)

Response Type: A 5-point Likert Type rating of confidence

0 = Not at all

1 = A little confident

2 = Moderately confident

3 = Quite confident

4 = Very confident

Sample items

1. You are having dinner with your family and your favorite meal has been prepared. You finish the first helping and someone says, "Why don't you have some more?" How confident are you that you would turn down a second helping?

5. You are invited to someone's house for dinner and your host is an excellent cook. You often overeat because the food tastes so good. How confident are you that you would not overeat as a dinner guest?

Subscales = 3

HCF = HIGH CALORIC FOOD TEMPTATIONS
SIF = SOCIAL AND INTERNAL FACTORS
NEE = NEGATIVE EMOTIONAL EVENTS

Reliability:

Test-retest correlations for a 2- to 3-week interval were rtt = .83 for the full scale. Subscale results were: HCF .75, SIF .77, NEE .80

Internal consistency values ranged from alpha = .82 to .87 for the full measure and for the subscales, alpha values were HCF .70-.77; SIF .71-79; NEE .75-.79.

See the Stich et al. (2009) reference for details.

Validity:

Construct validity was evaluated by factor analysis, which supported the three subscales. See the article for evidence of convergent and criterion-related validity.

Availability:

The article can be found in various databases. See Table 1 for the items.
