A Pilot Study on an ACT-Based Program for Individuals With Special Needs and Their Caregivers

Promoting Wellbeing and Personal Values: A Pilot Study on a Group-Based Program for Individuals With Special Needs and Their Caregivers

Parenting children with special health care needs can be stressful and weigh on the caregivers' mental health. For the individuals with special needs, the mismatch between their needs and the normative practice in the world around them can be frustrating and detrimental to their functioning. The demands and concerns to these families can be so real that it may not be sensible to examine the validity or helpfulness of the distressing thoughts or feelings but to promote psychological flexibility, which is a key to value-guided living. This pilot study explores the effects and feasibility of a group-based intervention for families of individuals with special health care needs.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Treatment
Acceptance and Commitment Therapy
Behavioral: Acceptance and Commitment Therapy
Acceptance and Commitment Therapy (ACT) is a well-established and evidence-based psychotherapy for individuals at different ages and with different clinical needs. The protocol used in the current study is adapted from an established local group intervention and tailored to families of individuals with special health care needs.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Psychological Flexibility as Measured by the Multidimensional Psychological Flexibility Inventory
Time Frame: From baseline (T0) to two (T1), four (T2), and six (T3; post-intervention) weeks into treatment
Score on psychological flexibility is the sum of scores across items
From baseline (T0) to two (T1), four (T2), and six (T3; post-intervention) weeks into treatment
Change from Baseline in Psychological Inflexibility as Measured by the Multidimensional Psychological Flexibility Inventory
Time Frame: From baseline (T0) to two (T1), four (T2), and six (T3; post-intervention) weeks into treatment
Score on psychological inflexibility is the sum of scores across items

Time Frame: From baseline to six weeks into treatment
Score on parenting stress is the sum of scores across items
From baseline to six weeks into treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Change from Baseline in Child Externalizing as Measured by the Strengths and Difficulties Questionnaire
Time Frame: From baseline to six weeks into treatment (i.e., post-intervention)
Score on externalizing is the sum of scores across items
