Planning and problem-solving training for patients with schizophrenia: a randomized controlled trial

Abstract

BackgroundThe purpose of this study was to assess whether planning and problem-solving training is more effective in improving functional capacity in patients with schizophrenia than a training program addressing basic cognitive functions.MethodsEighty-nine patients with schizophrenia were randomly assigned either to a computer assisted training of planning and problem-solving or a training of basic cognition. Outcome variables included planning and problem-solving ability as well as functional capacity, which represents a proxy measure for functional outcome.ResultsPlanning and problem-solving training improved one measure of planning and problem-solving more strongly than basic cognition training, while two other measures of planning did not show a differential effect. Participants in both groups improved over time in functional capacity. There was no differential effect of the interventions on functional capacity.ConclusionA differential effect of targeting specific cognitive functions on functional capacity could not be established. Small differences on cognitive outcome variables indicate a potential for differential effects. This will have to be addressed in further research including longer treatment programs and other settings.Trial registrationClinicalTrials.gov NCT00507988

Manual Dexterity in Schizophrenia—A Neglected Clinical Marker?

“…The above neuropsychological tests have been shown to be reliable and valid in schizophrenia (i.e., with test–retest correlation R  > 0.7 or Cronbach’s alpha > 0.7): selective attention, D2 test (56); WAIS-III (57); WCST (58); action planning, zoo map test (59); problem solving, D-KEFS Tower Test (60); Stroop (58). …”

Role of Executive Function in Response to a Problem Solving Based Psychoeducational Intervention in Adolescents with Psychosis: The PIENSA Trial Revisited

“…The core components of the problem-solving strategies [35] implemented in the PE group are described as follows [26,27,29]. (1) Clear definition of the dilemma.…”

“…They have traditionally included in these programs to enhance the patient's skills to cope and manage their daily life dilemmas. The aim is to assist participants to adapt to novel situations, orientating and redirecting their behavior in order to set and properly archive their goals by generating, evaluating, and choosing between alternative courses of action [26,27]. The inclusion of this key component in cognitive remediation programs has demonstrated greater positive effects than those approaches only based on "drill and practice" [28].…”

Functional capacity: a new framework for the assessment of everyday functioning in schizophrenia

“…[59][60][61][62][63][64][65][66][67][68] While the first report meeting these criteria was published in 2006, most of the remaining articles were published in the last 3 years, probably after the aforementioned recommendations were implemented by the FDA. Five of these trials were designed to evaluate the effects of drug therapy with atypical antipsychotics (risperidone, quetiapine, lurasidone), a neuropeptide (davunetide), or other potential cognitionenhancing drugs.…”
