Brief Summary

The objective of the study was to determine how patients with eating disorders perceive time, and in particular whether their experience of time differs from that of healthy individuals. Another goal was to examine the relationship between the mood of the subjects and their time perspective. The subjects were 30 women with eating disorders and 30 age-matched healthy female controls. The three measures applied were: the Time Metaphors Questionnaire by Sobol-Kwapinska, the Time Perspective Inventory by Zimbardo, and the UWIST Mood Adjective Checklist (UMACL) by Matthews et al.

Outcome Measures

Primary Outcomes (4)

  • The Time Metaphors Questionnaire by Sobol-Kwapińska

    The measure consists of 95 items formulated as metaphors describing ideas eliciting strong emotions. The subjects are asked to rate the items on a scale from 1 to 4, depending on the degree to which a given metaphor is consistent with their perception of time. The items are grouped into 3 scales reflecting positive attitudes to time: Friendly Time (subdivided into two subscales: Constructive Time and Pleasant Time), Significance of the Moment, and Subtle Time, as well as four scales covering negative attitudes to time: Hostile Time (with three subscales: Finiteness of Time, Bitter Time, and Confusion in Time), Rapid Passage of Time, Wild Time, and Empty Time. The questionnaire reveals satisfactory reliability and validity.

  • Time Perspective Inventory by Zimbardo

    The measure consists of 56 items which the respondents rate on a 5-point scale ranging from 1 (very uncharacteristic of me) to 5 (very characteristic of me). The questionnaire tests 5 time perspectives: 1) Past-Negative, 2) Past-Positive, 3) Present-Hedonistic, 4) Present-Fatalistic, and 5) Future. The Polish version of this instrument has been reported to have both good reliability and validity.

  • Transcendental Future Time Perspective Inventory

    This is a one-dimensional scale that consists of 10 items which the respondents rate on a 5-point scale ranging from 1 (very uncharacteristic of me) to 5 (very characteristic of me). It is used to assess individual attitudes and beliefs regarding the future, immediately following the imagined death of the physical body.

  • The UWIST Mood Adjective Checklist (UMACL) by Matthews et al.

    The instrument measures mood understood as an affective experience of a duration of at least several minutes; its three scales are Tense Arousal, Energetic Arousal, and Hedonic Tone. The UMACL consists of a list of 29 adjectives which the respondents rate in terms of applicability to their current mood on a four-point scale from definitely yes to definitely not. The reliability and validity of the Polish adaptation has been confirmed.

Eligibility Criteria

Age18 Years - 40 Years
Sexfemale
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

The clinical and control groups did not differ significantly in terms of age (t = 1.64, p = 0.100) or height (t = -0.54, p = 0.590). Obviously, significant differences were found in terms of weight and BMI (t = -2.93 and t = -3.03, p \< 0.01, respectively): women with eating disorders were much lighter (M = 50.78, SD = 13.05) and had a much lower BMI (M = 18.3, SD = 4.49) than healthy controls (M = 60.43, SD = 12.48, and M = 21.62, SD = 3.98, respectively). The mean duration of eating disorder was 8.9 years (SD = 5.23).

You may qualify if:

  • Clinical diagnosis of eating disorders (anorexia nervosa or bulimia nervosa)
  • Age between 18 and 40 years

You may not qualify if:

  • diagnosis of other (except eating disorders) mental disorder
  • Age below 18 years and above 40 years
