Perfectionism

Brief summary

The purpose of this study is to assess the effectiveness of CBT based online guided self-help intervention for perfectionism at reducing symptoms of perfectionism and Axis I disorders post-treatment and at six-month follow-up.

Detailed description

Perfectionism is elevated across, and increases risk for a range of Axis I disorders, as well as having a direct negative effect on day to day function. A growing body of evidence shows that cognitive behavioural therapy (CBT) reduces perfectionism and Axis I disorders, with medium to large effect sizes. Given the increased desire for online interventions to facilitate access to evidence-based therapy, web-based CBT self-help interventions for perfectionism have been designed. Existing interventions have not included personalised guidance which has been shown to improve outcome rates. The purpose of this study is to assess the effectiveness of CBT based online guided self-help intervention for perfectionism at reducing symptoms of perfectionism and Axis I disorders post-treatment and at six-month follow-up. A randomised controlled trial method is employed, comparing the treatment arm (online guided self-help) with a waiting list control group. Outcomes are examined at three time points, T1 (baseline), T2 (post-intervention at 12 weeks), T3 (follow-up at 24 weeks). Participants will be recruited through universities, online platforms, and social media, and if eligible will be randomised using an online automatic randomiser.

Design outcomes

Primary

MeasureTime frameDescription
Frost Multidimensional Perfectionism Scale (Frost et al., 1990)6 monthsThis self-report measure consists of 36 items grouped into six subscales. Participants respond on a five point scale ranging from 1 = strongly disagree to 5 = strongly agree. The measure has been found to be both reliable and valid for use with non-clinical and clinical populations (Frost et al., 1990; Hewitt & Flett, 1991; Hewitt, Flett, Turnbull-Donovan, & Mikail, 1991). Participants will be considered eligible for inclusion in the study if they score one standard deviation above published norms on the Concern over Mistakes subscale, i.e. a score of ≥ 29. This measure has been amended to reflect participants experience over the past month allowing us to measure change.

Secondary

MeasureTime frameDescription
Eating Disorder Examination-Questionnaire (EDE-Q) (C. G. Fairburn, 1994)6 monthsThe EDE-Q assesses for symptoms of the eating disorders: Anorexia Nervosa (AN), Bulimia Nervosa (BN), Binge Eating Disorder (BED) and sub-threshold variants. The measure consists of 28 items rated on a seven point scale appropriate to the item: number of days a symptom has been experienced over the past month, ranging from no days to every day; and for remaining questions (e.g. How dissatisfied have you been with your weight?) responses ranging from Not at all to Markedly. It has been found to have good reliability, and has been validated for use among clinical and community samples (Aardoom, Dingemans, Op't Landt, & Van Furth, 2012; Carter, Stewart, & Fairburn, 2001; J. M. Mond, Hay, Rodgers, Owen, & Beumont, 2004; Jonathan M Mond et al., 2008; Reas, Grilo, & Masheb, 2006).
Obsessive-Compulsive Inventory - Revised (OCI-R) (Foa et al., 2002)6 monthsThe OCI-R, a shortened version of the Obsessive-Compulsive Inventory, assesses symptoms of OCD. The measure consists of 18 items (e.g. I frequently have get nasty thoughts and have difficulty in getting rid of them). On a five point scale, respondents rate how distressed or bothered they have been in the past month by the symptom described, with responses ranging from Not at all to Extremely. It has been found to have good validity and reliability in both clinical and non-clinical samples (Abramowitz & Deacon, 2006; Foa et al., 2002; Hajcak, Huppert, Simons, & Foa, 2004; Huppert et al., 2007).
Depression, Anxiety and Stress Scales (DASS) (Lovibond & Lovibond, 1996)6 monthsThe DASS is a 42 item self-report measure of depression, anxiety and stress (e.g. I found myself getting upset by quite trivial things), rated on a four point scale ranging from Did not apply to me at all to Applied to me very much or most of the time. It has been shown to be reliable and has been validated for use among clinical and community samples (Brown, Chorpita, Korotitsch, & Barlow, 1997; Crawford & Henry, 2003; Page, Hooke, & Morrison, 2007).
Vancouver Obsessional Compulsive Inventory - Mental Contamination Scale (VOCI-MC) (Radomsky, Rachman, Shafran, Coughtrey, & Barber, 2014)6 monthsThe VOCI-MC is a self-report measure that assesses symptoms of mental contamination. The measure consists of 20 items (e.g. Often I look clean but feel dirty), rated on a five point scale ranging from Not at all to Very much. It has been shown to be reliable and valid for use among clinical and community samples (Coughtrey, Shafran, Knibbs, & Rachman, 2012; Coughtrey, Shafran, & Rachman, 2013; Radomsky et al., 2014).
Clinical Perfectionism Questionnaire (CPQ; C. Fairburn et al., 2003a)6 monthsThis self-report measure consists of 12 items (e.g. Have you pushed yourself really hard to meet your goals? and Have you raised your standards because you thought they were too easy?). Participants respond on a four point scale ranging from 1 = not at all to 4 = all the time. This measure of clinical perfectionism was created by Fairburn, Cooper and Shafran at the University of Oxford, and has been found to have good reliability and validity in two community samples and an ED sample; participants will be considered eligible for inclusion if they score similarly to this psychiatric population (i.e. a score of ≥ 29) (Egan, Shafran, et al., 2014). This measure has been amended to reflect participants experience over the past week, allowing us to monitor change on a weekly basis.

Other

MeasureTime frameDescription
Intolerance of Uncertainty Scale (IoU; (Freeston, Rhéaume, Letarte, Dugas, & Ladouceur, 1994)6 monthsThe IoU consists of 27 items (e.g. Uncertainty stops me from having a firm opinion and It's unfair not having any guarantees in life), and is rated on a five point scale ranging from 1 = Not at all characteristic of me to 5 = Entirely characteristic of me. It has been found to be reliable, and has been validated for use among clinical and community samples (Kristine Buhr & Dugas, 2002; Kristin Buhr & Dugas, 2006; Jacoby, Fabricant, Leonard, Riemann, & Abramowitz, 2013).
Warwick-Edinburgh Mental Well-Being Scale (WEMWBS; (Tennant et al., 2007)6 monthsThe WEMWBS is a 14 item self-report measure of mental well-being that focuses on positive aspects of mental health, including subjective well-being, psychological functioning (including autonomy, competence, self-acceptance, and personal growth), and interpersonal relationships. Examples of items include, I have been feeling optimistic about the future, I have been feeling confident, and I have been dealing with problems well. Participants respond on a five point scale, ranging from 1 = none of the time to 5 = all of the time. The WEMWBS has shown good reliability (0.83) and has been validated for use among student and population samples (Clarke et al., 2011; Maheswaran, Weich, Powell, & Stewart-Brown, 2012; Tennant et al., 2007).
Rosenberg Self-esteem Scale (Rosenberg, 1965)6 monthsThis measure of self-esteem consists of 10 items (e.g. On the whole I am satisfied with myself and I wish I could have more respect for myself) and is rated on a four point scale ranging from 1 = strongly disagree to 4 = strongly agree It has been found to be reliable, and been validated for use among clinical and community samples (Bagley & Mallick, 2001; Ferring & Filipp, 1996; Martín-Albo, Núñez, Navarro, & Grijalvo, 2007; Phillips, Pinto, & Jain, 2004; Schmitt & Allik, 2005; Shaw-Zirt, Popali-Lehane, Chaplin, & Bergman, 2005).
Fears of Compassion Scales (FCS; (Paul Gilbert, McEwan, Matos, & Rivis, 2011)6 monthsThis measure consists of three scales which assess fear of compassion for self (e.g. I worry that if I start to develop compassion for myself I will become dependent on it), fear of compassion from others (e.g. I try to keep my distance from others, even if I know they are kind), and fear of compassion for others (e.g. Being too compassionate makes people soft and easy to take advantage of). The FCS is made up of 38 items in total which are rated on a four point scale ranging from 0 = Don't agree at all to 4 = Completely agree. It has been shown to be reliable, and valid for use among clinical and community samples (P Gilbert et al., 2012; Paul Gilbert et al., 2011).
