“…Kitchen-related tasks may be gender oriented, which is a limitation for their use and validity and sensitivity, among others. In relation to the question about whether instruments with simulated tasks correlate well with performance in tests based on real performance, we found the following: a study conducted with patients with serious mental illness [118] showed that tasks simulated in controlled conditions were a strong predictor of performance in real-world tasks. This study also found that verbal memory correlated positively with independence in the community.…”

“…This study also found that verbal memory correlated positively with independence in the community. According to these authors, it is interesting to develop new systems for naturalistic evaluation, since most assessment tools available to date do not fully explain performance in the real world [118]. It is necessary to clinically validate all technologies and determine whether they have predictive validity over functional performance.…”

“…Among people with schizophrenia spectrum disorders, neurocognitive limitations have been identified as a key feature since the earliest descriptions of psychotic disorders by Kraepelin (1919). Thus, limitations in neurocognition cut across diagnoses within SMI and are implicated in health and function, as they affect functional competence (Gupta et al, 2013), skill performance in natural environments (Rempfer & Fowler, 2018), subjective quality of life (Hasson-Ohayon et al, 2017), and community functioning (Cook et al, 2013).…”

Objective: The purpose of this study was to determine if environmental novelty was associated with neurocognitive function among adults with serious mental illness. Method: Participants were recruited from community mental health centers (n = 117), and received a Global Positioning System (GPS) enabled cellular phone for 13 days. Data were also collected on cognitive function and recent participation in community-based activities. Independent samples t-tests were conducted to identify differences in neurocognitive function between participants who predominantly stayed in their homes ("homebodies") versus those who ventured more often from their homes ("venturers"). Analyses were also undertaken to identify if the nature of community participation activities mediated the relationship of neurocognitive function to group membership. Results: Overall, 74% of GPS signals were from participants' home residence. Homebodies demonstrated significantly poorer cognitive function than venturers, and this relationship was not mediated by a number of unique destinations or breadth of community participation activities. Conclusions and Implications for Practice: This study identified a subset of adults with serious mental illnesses who left their homes infrequently and who demonstrate significantly poorer cognitive function than those who left their homes more frequently. Spending extensive amounts of time in an unchanging environment may be a contributing factor to poor cognitive function, and a potential area for intervention. Impact and ImplicationsThis study found that among adults with serious mental illness, spending a majority of days never leaving the home was associated with poorer neurocognitive function. Given that neurocognition is known to respond to environmental demands, spending extended periods in a single home environment may provide little stimulation and hence little opportunity to support neurocognitive abilities.

“…This level of functional assessment is thought to capture functional capacity, or the ability to deploy functional skills under optimal conditions (Green et al, 2015), and demonstrates modest predictive utility in studies examining real-world functioning (Bowie et al, 2006). Skill assessment at the level of naturalistic performance has the potential to assist in identifying important abilities that cannot be captured by laboratory-based, functional capacity assessments of daily life functioning and may help to refine and develop models of everyday functioning (Rempfer & Fowler, 2018; Robertson & Schmitter-Edgecombe, 2017). For instance, the Test of Grocery Shopping Skills (TOGSS; Brown, Rempfer, & Hamera, 2009) is one such naturalistic assessment method and requires examinees to shop for 10 common grocery items in a real-world supermarket.…”

“…Nonetheless, as an in vivo, naturalistic test, TOGSS performance reflects the same cognitive and behavioral demands of everyday life. In prior work, naturalistic performance on the TOGSS has been found to distinguish persons with and without SMI (Hamera, Brown, Rempfer, & Davis, 2002), relate to neuropsychological functioning (Rempfer, Hamera, Brown, & Cromwell, 2003), and has been associated with functional capacity (Rempfer & Fowler, 2018) as well as grocery shopping in one’s everyday life (Faith & Rempfer, 2018).…”

Objective: To characterize variability in daily life functioning among individuals with serious mental illness based on a naturalistic performance measure of grocery shopping and standard neuropsychological tasks using cluster analytic methods. Methods: A naturalistic performance measure, the Test of Grocery Shopping Skills (TOGSS), and standard neuropsychological tasks, were completed by 191 participants with serious mental illness. Hierarchical cluster analytic techniques were used to explore functional subgroups based on naturalistic performance measure variables. Multivariate analyses of variance were utilized to compare subgroups on TOGSS variables and neuropsychological measures, respectively. Results: Two distinct functional subgroups emerged from the cluster analysis. On average, participants in cluster one were faster, more efficient, and more accurate compared to cluster two. Based on performance on neuropsychological tasks, cluster one had better verbal memory, visual attention, and processing speed, and executive functioning scores, compared to cluster two. The clusters did not differ on a measure of auditory working memory. Conclusions and Implications for Practice: Naturalistic performance measures can assist with characterizing the heterogeneity in real life functioning among people with serious mental illness. Further work to illuminate the relationship between specific cognitive abilities and specific functional abilities is warranted and may assist with targeting effective treatment plans for functional recovery.
