The Perceive, Recall, Plan and Perform (PRPP) system for persons with Parkinson's disease: a psychometric study

Using PRPP-Assessment for measuring change in everyday activities by home-based videos: An exploratory case series study in children with multiple disabilities

BACKGROUND

Currently, paediatric health care aims to use a child-centred tailor-made approach. In order to design tailored occupational therapy, the implementation of personalised occupation-based measurements that guide and evaluate goal setting and are responsive to change is necessary.

PURPOSE

Primarily, this study explored the potential of the Perceive, Recall, Plan, and Perform (PRPP) assessment to measure the change in the performance of children with multiple disabilities. As a secondary evaluation, the feasibility of the PRPP-Intervention in a home-based program to enable activities was described. The overall aim is to show the potential of the PRPP-Assessment as an outcome measure to use as a base for designing tailor-made person-centred care.

METHODS

An exploratory longitudinal multiple case series mixed-methods design was used. The PRPP-Assessment, scored by multiple raters, was conducted based on parent-provided videos. The assessed activities were chosen by the child and/or parents. Responsiveness was evaluated by hypotheses formulated a priori and by comparing measured change with change on concurrent measures: Goal Attainment Scaling (GAS) and Canadian Occupational Performance Measure (COPM). Over a 6-week period, children and their parents (or caregivers) participated in an online home-based video coaching program where parents were coached in the implementation of the training, based on the PRPP-Intervention, by paediatric occupational therapists on a weekly basis. The feasibility of the intervention was explored using semi-structured interviews with children, parents, and the treating occupational therapists and was analysed by directed content analysis.

RESULTS

Three out of 17 eligible children agreed to participate and completed post-intervention measurement, of which two completed the intervention. Quantitative results showed that eight out of nine activities improved on the PRPP-Assessment and the COPM, and nine improved on the GAS. In total, 13 out of 15 hypotheses for responsiveness were accepted. Participants experienced the intervention as successful and acceptable. Facilitators and concerns over demand, implementation, practicality, integration, and adaptation were shared.

CONCLUSION

The PRPP-Assessment showed the potential to measure change in a heterogeneous group of children. The results indicated a positive tendency for the intervention and also provide directions for further development.

Effectiveness of the Perceive, Recall, Plan and Perform intervention for persons with brain injury in community-based rehabilitation: protocol for a single-case experimental design with multiple baselines

INTRODUCTION

There is a need for standardised interventions in community-based rehabilitation to improve everyday performance for older adults with cognitive challenges due to acquired brain injury (ABI). The Perceive, Recall, Plan and Perform System (PRPP) of intervention has a growing research base. The intervention is suitable for any client with decreased performance in everyday tasks due to ineffective cognitive strategy application to enhance mastery in performance of needed or desired activities. There is no current evidence on the effectiveness of the PRPP intervention for this population.

PURPOSE

To describe a protocol for a clinical trial that investigates the effectiveness of the PRPP intervention in the context of community-based rehabilitation for persons (65+ years) with difficulties in task performance due to cognitive challenges after ABI.

METHODS AND ANALYSIS

A non-concurrent multiple baseline design across participants with systematic replications (n=6) will be used. Nine sessions of PRPP intervention will be applied by trained occupational therapists in two community-based rehabilitation units. The participants will complete five repeated measurements of everyday tasks as target behaviours. PRPP Assessment stages 1 and 2 serve as outcome measures at baseline, in the intervention period, in the postintervention period and in the follow-up phase. Mastery percentage of the tasks and the participants' application of cognitive strategies at baseline acts as a control and will be compared with the following phases within the participant. Delayed intervention phases act as a control between participants. Goal Attainment Scaling and the Barthel Index will serve as generalisation measures. Data will be analysed using systematic visual inspection of graphical data, descriptions of clinical significance and descriptive statistical analysis.

ETHICS AND DISSEMINATION

This trial, including the data management plan, is approved by The Norwegian Regional Ethics Committee (215391). Results will be published in congresses and scientific journals.

The reliability and validity of the perceive, recall, plan and perform assessment in children with a mitochondrial disorder

PURPOSE

To investigate the reliability and validity of the Perceive, Recall, Plan and Perform System of Task Analysis (PRPP-Assessment) by parent-provided videos of children with mitochondrial disorders.

METHODS

Videos of 13 children performing 3-7 activities each were the subject of study, resulting in 65 activities. These were scored using the PRPP-Assessment by 11 raters. Internal consistency was calculated with Cronbach's alpha. Intra-rater reliability was evaluated by Bland-Altman Plots on 44 PRPP-Assessment scores. Inter-rater reliability was calculated with ICC_Agreement on 128 PRPP-Assessment scores. Construct validity was assessed by comparing the PRPP-Assessment scores to the Canadian Occupational Performance Measure using Cohen's Kappa. PRPP-Assessments scores were evaluated with a multi-faceted Rasch Analysis.

RESULTS

Internal consistency was high (0.92). Intra-rater reliability was sufficient to be good (92-96% within the 95%-Limits of the Agreement). The ICC_Agreement for stage 1 Mastery Score showed acceptable inter-rater reliability (0.646). Stage 2 of the PRPP-Assessment showed low ICCs due to a lack of variability within the sample. Four out of six hypotheses on validity were accepted. Rasch's analysis demonstrated sound goodness-of-fit, and supported the validity of the PRPP-Assessment.

CONCLUSION

The PRPP-Assessment by parent-provided videos in this heterogenic group showed sufficient to good psychometric properties. In practice, careful task selection and formulating criterion is recommended.Implications for RehabilitationPRPP-Assessment by parent-provided videos is reliable and valid in the complex, heterogenous group of children with mitochondrial disordersThe PRPP-Assessment is suitable for children with mitochondrial disorders as it showed to contain familiar, functional and meaningful tasks and activities that fit with their level of functioningProfessionals should be aware that parents might not be used to the criterium-based frame of reference of the PRPP-AssessmentWhen applying the PRPP-Assessment, it is recommended to be careful in task selection and formulating the criterion.

Stroke survivors’ occupational performance and cognitive strategy use: A pilot exploration of strengths and difficulties using the Perceive Recall Plan Perform System of Task Analysis

Introduction

The Perceive Recall Plan Perform System of Task Analysis is an ecological assessment of occupational performance and cognitive strategy application. This study aimed to describe occupational performance and cognitive strategies of stroke survivors in an early supported discharge service, compare the assessment with global measures of function and evaluate the feasibility of implementing the assessment in the early supported discharge setting.

Method

This study was a pilot study design and used consecutive sampling. Participants were assessed with the Perceive Recall Plan Perform System of Task Analysis and two global measures: the Functional Independence Measure and the Australian Modified Lawton’s Instrumental Activities of Daily Living Scale. Scores from the Perceive Recall Plan Perform System of Task Analysis were analysed by task mastery, sub-quadrants and quadrants, and correlations between the assessment and global measures were examined.

Findings

In this cohort ( n = 10), the Perceive Recall Plan Perform System of Task Analysis assessment required 47 minutes per task and identified reduced task mastery (mean = 55%, SD = 10%) with common difficulties in the perceive and plan domains. High to moderate correlations were identified between the plan quadrant and global measures ( p < 0.05).

Conclusion

Perceive Recall Plan Perform System of Task Analysis assessment can be successfully implemented by occupational therapists with stroke survivors receiving early supported discharge to measure occupational performance and identify strengths and difficulties in cognitive strategy application.

How to evaluate effects of occupational therapy - lessons learned from an exploratory randomized controlled trial

BACKGROUND

Although occupational therapy (OT) is frequently prescribed in clinical practice, there is still insufficient evidence regarding its efficacy to improve Parkinson's Disease (PD)-related activity limitations.

OBJECTIVES

To evaluate the efficacy of OT and the validity of different outcome-parameters to reflect efficacy, including gold-standard clinical rating scales and quantitative motor assessments.

METHODS

40 patients were included in an exploratory, randomized-controlled, single-blinded trial, receiving either (I) ten weeks of OT, with a main focus on motor aspects of activity limitations and a ten-week follow-up assessment or (II) no intervention. Inclusion criteria were diagnosis of PD and Hoehn & Yahr stage 2-3. Patients with major depression, other neurological or orthopedic diseases or OT beforehand were excluded from the study. To monitor treatment effects the MDS-UPDRS part II and III were used for patient- and clinician-based assessment. Objective Pegboard as well as Q-Motor "tremormotography" and "digitomotography" were applied.

RESULTS

The interventional group reported a subjective amelioration of activity limitations, with a significant improvement of MDS-UPDRS part II at the end of the study (p = 0.030). However, clinician's rating and quantitative motor assessment failed to detect a significant improvement of motor impairment and fine motor control.

CONCLUSIONS

This study goes in line with previous trials, showing an individual improvement of activity limitations from the patients' point of view. The discrepancy between self-perception, focusing on activity limitation, and clinician-based rating, focusing on motor impairment, challenges the current gold standard assessments as valid outcome parameters for occupational therapy trials aiming for an individualized improvement of disease burden.
