Overview

Brief Summary

This study investigates the utility of Goal Management Training (GMT) in patients with post-traumatic stress disorder (PTSD), in order to determine if this treatment is effective in improving cognitive function in patients with frontal-temporally mediated brain dysfunction. Specifically, the primary aim of this study is to examine whether a standardized 9-week program of GMT results in durable improvements in cognitive functioning relative to a wait-list control group. A secondary aim will be to determine whether participation in the GMT group is associated with long-term functional improvements. It is hypothesized that at post-treatment, participants with PTSD assigned to the GMT groups will show greater improvement in neuropsychological test performance and greater functional improvement compared to those in the wait-list group; these gains are expected to be maintained at 3 month follow-up.

Detailed Description

Given the potentially devastating impact of poor cognitive functioning on the ability of patients with PTSD to benefit from treatment interventions, and its association with poor functional outcomes, there is an urgent need to identify novel treatment interventions aimed at reducing cognitive dysfunction in these disorders. Accordingly, the aim of the present proposal is to conduct a randomized controlled trial among patients with PTSD, examining the efficacy of a well-established cognitive intervention (in the treatment of cognitive deficits), aimed at reducing attentional and executive dysfunction, known as Goal Management Training® (GMT) (See Levine et al., 2011). A secondary aim is to determine the longer-term impact of the GMT approach on functional outcomes. The participants include 48 men and women with a primary diagnosis of with stable symptoms at the time of baseline assessment and reporting alterations in memory, attention, or executive functioning. Participants will be recruited from multiple sites: an inpatient post-traumatic stress recovery program in Ontario, Canada, and the program's external referral agencies that also service clients via outpatient services/ programs, external community agencies and support groups, and through social media. Following determination of eligibility, participants will be randomly assigned, by using the randomized table of numbers method, to either: 1) a 9-week GMT program or 2) a 9-week wait-list control (WLC) condition (see Figure 1). Participants will be invited to attend a baseline testing session 1 prior to group commencement (approximately 4 hours in duration) where written consent will be obtained prior to any collection of data. Once the testing session is complete, the participants will be given information about what group they have been assigned to (GMT or WLC). Participants enrolled in the GMT program attended the 9-week GMT sessions (2 hours/week for 9 weeks) and a post-intervention testing session date (1-2 weeks following the completion of the GMT; approximately 3 hours in duration). Participants enrolled in the WLC control group attended a testing session date after 9 weeks has past (approximately 3 hours in duration). As each participant completed a post-intervention testing session (both GMT and WLC), they will be setup with the final testing session (in 3 months' time; approximately 3 hours in duration). WLC were offered a complimentary 9-week GMT program once the final testing session is complete. Following the completion of the complimentary 9-week GMT program, individuals in the WLC completed a post-intervention testing (1-2 weeks following the completion of GMT and again at 3 months, post GMT completion). These data will be analyzed using 2 x 3 mixed-design split plot factorial ANCOVAs that treat Group (GMT vs. WLC) as a between-subjects factor and Time (baseline, post-intervention, 3 months; subjects nested within groups) as a within-subjects factor. In addition, within-subjects analyses of covariance (ANCOVAS) treating time (baseline, post-intervention, 3 months) as a within-subjects factor will be carried out on data collected from the GMT group and from the WLC group after they have completed the GMT arm of the study. PTSD symptom severity (CAPS), depressive symptom severity (BDI-II), severity of past trauma exposure (CTQ), and medication load, and additional psychological treatment (treatment information form) will serve as covariates in this model. Tukey's Honestly Significant Difference post-hoc test will be used for follow-up pair-wise comparisons of between-subjects' variables. It is hypothesized that, post-treatment, participants with PTSD assigned to the GMT group will show significantly greater improvement in neuropsychological test performance and greater functional improvement compared to participants in the wait-list control group; these gains are expected to be maintained at 3-month-follow-up.

Outcomes

Primary Outcomes

Change in score on Controlled Oral Word Association Task (COWAT)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

A neuropsychological assessment of verbal fluency, in which participants are asked to name as many words beginning with "F", "A", and "S" (Subscale: FAS). For each letter, they are given one minute to complete the task. Following this, the participant is required to name as many animals as they can within one minute (Subscale: Animals). Scores are calculated by adding unique words across FAS, and within Animals. These raw scores (i.e., FAS raw and Animals raw) are converted to scaled scores (i.e., FAS Scaled Score and Animals Scaled Score), which range between 0 and 19. The scaled scores are then converted to T scores (i.e., FAS T Score and Animals T Score), which range between 0 and 100. The T scores are corrected for sex, age, education, and ethnicity. Higher T scores indicate greater verbal fluency performance.

Wechsler Abbreviated Scale of Intelligence - II (WASI-II): Vocabulary and Matrix Reasoning Subtests

Time Frame: Administered to GMT participants and Waitlist Participants only at baseline.

The WASI-II is a brief neuropsychological assessment aimed to provide an estimate of current intellectual functioning. The two-subtest form of the WASI-II consists of Vocabulary and Matrix Reasoning and provides a Full Scale IQ (FSIQ-2). In the Vocabulary subtest, participants give oral definitions for words (total raw scores may range between 0 and 59). For Matrix Reasoning, the participant looks at a matrix with a section missing and identifies the missing section by pointing to or stating the number of their response (total raw scores may range between 0 and 30). The subtests' total raw scores are converted to age-corrected T scores (T scores may range between 20 and 80 for each subtest). The FSIQ-2 is the sum of T scores on Vocabulary and Matrix Reasoning. FSIQ-2 scores may range between 45 and 160, with higher FSIQ-2 scores indicating higher intelligence.

Change in score on Stroop Colour and Word Test

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

A neuropsychological assessment of processing speed (word and colour reading) and sensitivity to suppress habitual responses.The test produces the following scores: i) Word-Reading Score, which is the raw score that consists of the number of items completed in 45 seconds. ii) Colour-Naming Score, which is the raw score that consists of the number of items completed in 45 seconds. iii) Colour-Word Score, which is the raw score that consists of the number of items completed in 45 seconds, and iv) Interference Score, which is derived by subtracting a Predicted Colour-Word Score (obtained from the Stroop Manual) from the raw Colour-Word Score. Scores are then translated into T scores using a table obtained from the Stroop manual. Values for these T scores range between 3-98, and 21 and 80 for the Predicted Colour-Word Score. Overall, higher T scores indicate greater processing speed and ability to suppress habitual responses.

Change in Score on Multidimensional Scale of Independent Functioning (MSIF)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

A semi-structured interview assessing participant report of i) work (e.g., competitive, supported, dependent care, volunteer); ii) education (e.g., college, vocational, certificate school, rehabilitation training program); and iii) residential activities (e.g., where the participant is living, what responsibilities the participant has). Each domain (i.e., work, education, and residential activities) is assessed according to role position, support, and performance. Scores for these areas may range between 1 and 7, with higher values indicating greater impairment in functioning. Furthermore, a global rating for role position, support, performance, and overall functioning is given. Scores for the global ratings also may range from 1 to 7, with higher values indicating greater impairment in functioning.

Change in Score on World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

The WHODAS 2.0 is a 12-item self-report measure of six functional domains, including cognition, mobility, self-care, getting along with others, life activities, and participation in the community. The WHODAS 2.0 uses a Likert scale ranging from 0 ("No difficulty") to 4 ("Extreme difficulty or cannot do"). Values across the 12 items are summed, with the total score ranging between 0 and 48. Higher values indicate greater functional impairment.

Change in score on Delis-Kaplan Executive Function System (D-KEFS) Tower Test

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

A neuropsychological assessment of planning, rule learning, response inhibition, and perseveration. Six scores are calculated: i) Total Achievement Score, which is the sum of achievement scores for all items administered. ii) Mean First-Move Time which reflects the average of the examinee's first move times. iii) Time-Per-Move Ratio, which indicates the average time the examinee takes to make each of his or her moves. iv) Move Accuracy Ratio is a means of assessing the efficiency with which the examinee constructed the towers. v) Total Rule Violations represents the total number of rule violations committed by the examinee across all items administered. vi) Rule-Violations-Per-Item Ratio, reflects the average number of rule violations made by the examinee relative to the number of items administered. The total number of rule violations across all items administered is divided by the number of items administered. Higher scores indicate greater executive functioning performance.

Change in score on Trail Making Test Part A & B (TMT A & TMT B)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

A neuropsychological assessment in which participants are required to sequence two stimulus sets while alternating between them. Scoring is expressed in terms of the time in seconds required for completion of each of the two parts of the test (i.e., TMT A and TMT B). The raw scores for each part of the test are translated to scaled scores (i.e., TMT A Scaled Score and TMT B Scaled Score) and scaled scores may range between 0 and 19. The scaled scores are then translated to T scores (i.e., TMT A T Score and TMT B T Score) corrected for sex, age, education, and ethnicity. The T scores may range between 0 and 100. Individuals with higher T scores indicate better attention, mental flexibility, and speed in comparison to those with lower T scores.

Change in score on Wechsler Adult Intelligence Scale-IV (WAIS-IV), Coding Subtest

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

A neuropsychological assessment of processing speed. In a time limit of 120 seconds, the participant copies symbols that are paired with numbers based on a symbol key. The total raw score is calculated by scoring 1 point for each correctly drawn symbol completed within the time limit. Raw scores range between 0 and 135 points. The raw score is converted to a scaled score corrected for age and the scaled score may range between 1 and 19. Higher scaled scores indicate greater processing speed than lower scaled scores.

Change in score on California Verbal Learning Test II (CVLT-II)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

A word list neuropsychological assessment, which provides indices of immediate and delayed memory performance, interference learning, and recognition. Software is utilized to score the CVLT-II, which computes all raw scores and standardized scores, corrected for the examinee's age and gender. Values of interest within the study include: i) Level of Immediate Recall; ii) Level of Delayed Recall, iii)Learning Characteristics, iv) Recall Errors, and v) Delayed Recognition Trials. In general, higher standard scores indicate intact performance; however, in other cases (e.g., Recall Errors) higher standard scores reflect greater deficits.

Change in Score on Cognitive Failures Questionnaire (CFQ)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months). Also GMT sessions 1,3,6, and 9

The CFQ is a 25-item self-report measure that captures daily errors in distractibility, blunders, names, and memory. Each item is rated on a Likert scale from 0 ("Never") to 4 ("Very often"). The CFQ has four subscales that include: i) Memory (i.e., sum of scores on items 16, 18, 12, 17, 23, 13, 6, 3 for a total score between 0 and 32); ii) Distractibility (i.e., sum of scores on items 1, 15, 2, 19, 21, 22, 3, 4, 25 for a total score between 0 and 36); iii) Blunders (i.e., sum of scores on items 9, 8, 10, 24, 5, 14, 11 for a total score between 0 and 28); and iv) Names (i.e., sum of scores on items 20 and 7 for a total score between 0 and 8). The CFQ total score is the sum of the 25 items, with total values ranging between 0 and 100. Higher scores indicate greater self-reported impairment in cognitive functioning.

Change in score on Conners Continuous Performance Task Third Edition (CPT-III)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

A neuropsychological assessment of inattentiveness, impulsivity, sustained attention, and vigilance. Values include: i) D-prime-discrimination of non targets from targets; ii) Omissions- all missed targets; iii) Commissions- all incorrect responses to non-targets; iv) Perseverations- response in less than 100 milliseconds following the presentation of a stimulus; v) Hit Reaction Time- mean response speed measured in milliseconds for all non-perseverative responses made during the entire administration; vi) Hit Reaction Time SD-consistency of response speed to targets for the entire administration; vii) Variability- response speed consistency; viii) Hit Reaction Time Block Change- slope of change in Hit Reaction Time across the six blocks of the administration; and ix) Hit Reaction Time Inter-Stimulus Interval Change- slope of change in reaction time across the three inter-stimulus intervals. All scores are presented in T scores with higher T scores indicating worse performance.

Change in score on Rivermead Behavioural Memory Test Second Edition (RBMT-II) Prospective Memory Tasks

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

Participants will be asked to complete two prospective memory tasks (Belongings and Appointments) where they will be given specific instructions and asked to independently act on these instructions at specific time points throughout the testing. Raw scores for Belongings and Appointments will be assessed. The raw score for Belongings may range between 0 and 8, while the raw score for Appointments may range between 0 and 4. Higher raw scores indicate better recall.

Wechsler Test of Adult Reading (WTAR)

Time Frame: Administered to GMT participants and Waitlist Participants only at baseline.

The WTAR assesses premorbid intellectual functioning in adults. The WTAR requires the participant to read out loud irregularly spelled words. The raw score ranges between 0 and 50. The WTAR raw score is converted to a standard score and the standard score may range between 50 and 134. Intelligence scores are also predicted by WTAR performance and demographics and intelligence scores may range between 89 and 118. Higher intelligence scores indicate greater premorbid intellectual functioning.

Change in Score on Sheehan Disability Scale (SDS)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

The SDS is a 3-item self-report measure of disability in work, social relationships, and family life. The three items, which are scored on a Likert scale between 0 and 10, are summed into a single dimensional measure of global functional impairment. The SDS total score may range from 0 to 30, with higher scores indicating greater impairment.

Change in Score on Goal Attainment Scaling (GAS)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

Description: The GAS is a method for defining individual participant goals and the standardized measurement of progress towards these goals. Overall goal attainment is transformed into a T score, with higher T scores indicating greater goal attainment.

Change in Score on Dysexecutive Questionnaire (DEX)

Time Frame: GMT group: Baseline, post-treatment (9 weeks), and 3 months. Wait list control: Baseline, post 9 week delay period, post 3 month delay period, post GMT (8 months), 3 months post-treatment (11 months)

The DEX is a 20-item self-report measure that asks participants to rate inhibition, positive and negative affect, memory, and intention. Each item is rated on a Likert scale from 0 ("Never") to 4 ("Very often"). The DEX Total score is the sum of all items and the total score may range from 0 to 80. Higher scores indicate greater self-reported cognitive impairment.
