This is a condensed version of the 1999 Outcome Report which can be found in its entirety on the Center for Change Web Site: http://centerforchange.com/articles/1999patients.php
At Center for Change, we use a variety of measures to assess patients’ progress. We assess specific eating disorder symptomatic behaviors such as bingeing, purging, and food restriction as well as beliefs about food, dieting, body shape, and so on. We also assess patients’ general psychological and spiritual functioning by using measures of depression, anxiety, self-esteem, interpersonal relations, social role functioning, loneliness, and spiritual well-being. All patients are assessed on the above dimensions when they are admitted to our inpatient treatment program and, if possible, when they are discharged from the program.
The following outcome summary documents the types and amounts of change for patients who were admitted to the Center for Change inpatient treatment program from January 1, 1999 through December 30, 1999. The analyses and conclusions presented are based on the 57 patients who completed outcome measures both at admission (pre-treatment) and discharge (post-treatment).
Center for Change Inpatient Demographics, 1
All Center for Change patients in 1999 were female. Twenty-three patients were diagnosed with Anorexia Nervosa, 20 with Bulimia Nervosa, and 18 with Eating Disorder (NOS). Fifty-eight patients were also diagnosed with additional Axis I disorders, the most common of which were Mood Disorders (depression and/or anxiety disorders). Ten patients were also diagnosed with an Axis II Personality Disorder. The average age of the patients was 21 years; the age range was 14 to 46 years. All 60 patients were Caucasian. In regards to religious affiliation, 35 patients were Latter-day Saints, 6 were Protestant, 4 were Roman Catholic, and the affiliation of 13 patients was unknown. Fifty patients were single, 5 were married, and 4 were divorced. Thirty-two patients were college graduates, 12 had completed some college, 9 had completed high school, and 3 had not yet graduated from high school.
The Center for Change treatment program milieu helps most patients gain control of and cease their disordered eating behaviors. This conclusion is substantiated further by the data presented in Figure 1. Here it can be seen that on the Eating Attitudes Teat (EAT), a standardized measure of eating disorder symptoms (e.g., anxiety about eating, preoccupation with food, vomiting, dieting, weighing oneself frequently, etc.). Center for Change patients’ scores declined from 61.69 before treatment to 16.82 after inpatient treatment.
This is a very large decline in eating disorder symptoms and concerns; in fact, scores falling below the line drawn horizontally across the graph fall into the normal range (that is, women without eating disorders score 30 and below on the EAT). Thus, on the average, when they complete inpatient treatment, Center for Change patients’ concerns about food, dieting, and weight are much less intense and are within the normal range for women.

Before Treatment After Treatment
On the Body Shape Questionnaire, a standardized measure of women’s concerns about their body shape and size (e.g., feeling too fat, wanting to be thinner, feeling ashamed of one’s body, etc), Center for Change patients’ scores declined from 145.4 to 88.8. This is a large decline, and it can again be seen that on the average, when they complete inpatient treatment, Center for Change patients’ concerns about their body shape and size are much less intense and are within the normal range for women.
On the Outcome Questionnaire (OQ45.2), a standardized measure of psychiatric symptoms (i.e., depression, anxiety, and substance abuse – see figure 2), interpersonal relationship distress (i.e., conflict and distress in relationships with family, spouse, and friends), and social role conflict (i.e., distress and inadequacy about one’s ability to perform social roles (i.e., at work, home, and in recreational settings), Center for Change patients’ scores declined from being clinically elevated (abnormal, disturbed range) to normal ranges.

Before Treatment After Treatment
Thus, after participating in the Center for Change inpatient program, on the average, Center for Change patients’ psychiatric symptoms, interpersonal relationship distress, and social role conflict were all much less intense and were comparable to those of normal functioning people.
On the Multidimensional Self-Esteem Inventory, a standardized measure of self-esteem (e.g., liking oneself, feeling lovable and accepted, perceiving oneself as competent, etc), Center for Change patients’ scores increased from a very low average score of 28.1 to an average score of 45.6, which is within the normal range. Thus, after participating in the Center for Change inpatient program, on the average, Center for Change patients’ feelings of self-esteem had improved significantly and were more comparable to the feelings of self-esteem reported by normal functioning college students.
On the Existential Well-Being subscale of the Spiritual Well-Being Scale, a standardized measure of life satisfaction and life direction (e.g., feeling satisfied with one’s life and the direction it is headed, feeling a sense of purpose and meaning in one’s life), Center for Change patients’ scores increased from 38.3 to 47.5. This is a sizable increase and indicates that the patients’ feelings of life satisfaction and life direction became more positive and fell in the normal range after they had completed the Center for Change inpatient treatment program.
Figure 3 illustrates that on the Religious Well-Being subscale of the Spiritual Well-Being Scale, a standardized measure of how people feel about their relationship with God (i.e., they believe that God loves them and is concerned about their well-being, they feel close to God and receive strength and comfort from their relationship with God), Center for Change patients’ scores increased from 43.2 to 49.7. This is a sizable increase and indicates that the patients’ feelings about their relationship with God became more positive and fell in the normal range after they had completed inpatient treatment at the Center for Change.

(e.g., feelings of love and closeness to God, believing that God is concerned and supportive)
Before Treatment After Treatment
When evaluating the average “frequency of clients’ thoughts” about various unhealthy eating and dieting practices (e.g., thoughts about bingeing, vomiting, using laxatives, etc.) reported the first week of their admission compared to the last week they were in the inpatient program, it can be seen that the frequency of patients’ thoughts about unhealthy eating and dieting behaviors significantly declined during their stay in the inpatient program. By the time patients were discharged from Center for Change, most of them rarely had thoughts about bingeing, purging, using laxatives, and so on. Not only were the reductions in frequencies of these thoughts statistically significant, but they were of the magnitude that we can conclude that the reductions in unhealthy thinking were clinically significant. 2
The weekly frequency of unhealthy eating and dieting behaviors also significantly declined according to patients’ self-reports. As a group, the patients reported that they no longer vomited or used diet pills and laxatives. They also reported that they rarely binged, used enemas, restricted eating, spit out food, or skipped meals during the last week of treatment.
Two standardized measures of attitudes and beliefs about eating, dieting, and body shape were also administered, the Eating Attitudes Scale and Body Shape Questionnaire. Again, the patients showed statistically and clinically significant improvement on both of these measures suggesting that, on the average, patients acquired much healthier attitudes and beliefs about food, dieting, and body shape during their inpatient stay at the Center.
An examination of the means, standard deviations, and t-values from patients’ self-reports regarding their psychological and interpersonal functioning reveals that the patients experienced, on the average, statistically and clinically significant improvement in their psychological and social functioning. The patients’ level of symptom distress (depression and anxiety) as measured by the OQ-45 outcome scale significantly declined. The patients’ level of psychological symptoms and distress had improved to normal levels at the time they were discharged from the Center’s inpatient program. They had also shown significant improvements in their interpersonal relations and feelings about their ability to perform normal social roles-in fact, their scores again fell into the normal ranges on these scales. The Multidimensional Self-Esteem Inventory results indicate that the patients’ feelings of self-esteem, self-worth, and feelings of capability and competence significantly improved during their inpatient stay. In light of the clinical observation that low self-esteem and feelings of self-hate seem to be one of the root causes of eating disorders, the finding that the patients significantly improved in their self-esteem would seem to bode well for their continued growth and long-term progress.
The Attitudes Towards Parents results indicates that the patients’ attitudes towards their mothers significantly improved during treatment (became less negative and resentful). The patient’s attitudes towards their fathers also slightly improved, although these changes were not statistically significant.
The patients’ scores on the Religious Well-Being scale significantly increased which indicates that the patients felt more positively about their relationship with God (they feel that God loves and helps them) at the conclusion of treatment compared to the start of treatment. The patients’ scores on the Existential Well-Being scale also significantly increased which indicates that the patients felt more meaning and purpose in their lives, and felt better about the direction their lives are headed, compared to the start of treatment.
In conclusion, the outcome data collectively provide strong evidence that the majority of Center for Change patients got significantly better during their inpatient stay at the Center. A small number of patients showed little improvement during their stay, but most of the patients made statistically and clinically significant improvements in terms of their disordered eating behaviors, beliefs, and attitudes as well as in their psychological, social, and spiritual functioning and well-being. Compared to the outcome data from 1996, 1997 and 1998, the patients that received treatment during 1999 as a group showed somewhat greater improvements on most measures, which supports the idea that the Center’s inpatient program further improved in its effectiveness during 1999. These data also provide evidence that the Center’s inpatient program successfully achieved its purposes with the majority of patients. That is, for most patients, the inpatient program gave them a “jump start” toward a healthier life by helping them make some significant changes in a short period of time.
1 Note: Numbers do not necessarily add up to 60 because some demographic data was not available for all patients.
2 Many of the reductions were close to or more than one standard deviation units in magnitude which is considered a large effect size; for example, a change of .85 standard deviation units indicates that at the end of treatment, the average treated person is better off than 80 percent of untreated patients (see Lambert & Bergin, Handbook of Psychotherapy and Behavior Change, Allen E. Bergin and Sol L. Garfield (Eds.), 1994, Wiley, New York, pp. 143-189).
