Objective:
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder commonly associated with relative impairments on processing speed, working memory, and/or executive functioning. Anxiety commonly co-occurs with ADHD and may also adversely affect these cognitive functions. Additionally, language status (i.e., monolingualism vs bilingualism) has been shown to affect select cognitive domains across an individual’s lifespan. Yet, few studies have examined the potential effects of the interaction between anxiety and language status on various cognitive domains among people with ADHD. Thus, the current study investigated the effects of the interaction of anxiety and language status on processing speed, working memory, and executive functioning among monolingual and bilingual individuals with ADHD.
Participants and Methods:The sample comprised of 407 consecutive adult patients diagnosed with ADHD. When asked about their language status, 67% reported to be monolingual (English). The Mean age of individuals was 27.93 (SD = 6.83), mean education of 15.8 years (SD = 2.10), 60% female, racially diverse with 49% Non-Hispanic White, 22% Non-Hispanic Black, 13% Hispanic/Latinx, 9% Asian/Pacific Islander, and 6% other race/ethnicity. Processing speed, working memory, and executive function were measured via the Wechsler Adult Intelligence Scale-Fourth Edition Processing Speed Index, Working Memory Index, and Trail Making Test B, respectively. Anxiety was measured via the Beck Anxiety Inventory (BAI). Three separate linear regression models examined the interaction between anxiety (moderator) and cognition (processing speed, working memory, and executive function) on language. Models included sex/gender and education as covariates with Processing Speed Index and Working Memory Index as the outcomes. Age, sex/gender, and education were used as covariates when Trail Making Test B was the outcome.
Results:Monolingual and bilingual patients differed in mean age (p < .05) but did not differ in level of anxiety, education, or sex/gender. Overall, anxiety was not associated with processing speed, working memory, and executive function. However, the interaction between anxiety and language status was significantly associated with processing speed (ß = -0.37, p < .05), and executive functioning (ß = 0.82, p < .05). No associations were found when anxiety was added as a moderator for the associations between language and working memory.
Conclusions:This study found that anxiety moderated the relationship between language status and select cognitive domains (i.e., processing speed and executive functioning) among individuals with ADHD. Specifically, anxiety had a greater association on processing speed and executive functioning performance for bilinguals rather than monolinguals. Future detailed studies are needed to better understand how anxiety modifies the relationship between language and cognitive performance outcomes over time amongst a linguistically diverse sample.

Objective:
Individuals with chronic pain frequently report diminished cognitive functioning. Prior cross-sectional studies have demonstrated strong associations between chronic pain and neurocognitive impairment, most notably in memory, attention, processing speed, and executive functioning. However, there is a paucity of research evaluating visual learning and memory abilities in this population. Further, while current practice standards advocate for the use of performance validity tests (PVTs) to assess the credibility of neuropsychological test performance, they have infrequently been incorporated into studies examining chronic pain samples, despite a higher observed rate of noncredible performance in the literature. This study aimed to compare visual learning and memory performance between a mixed neuropsychiatric (MNP) group and a chronic pain group in a validity-controlled sample.
Participants and Methods:The study consisted of 371 adults referred for outpatient neuropsychological evaluation. Between groups, various PVTs were administered, which included, at minimum, one freestanding and four embedded PVTs. All patients were administered the Brief Visuospatial Memory Test-Revised (BVMT-R) as part of a comprehensive neuropsychological evaluation. Only patients classified as valid performers (<1 PVT fails; n=295) were included in the analyses (Pain: n=109; MNP: n=186). The overall sample was 69% female and racially diverse (22% non-Hispanic Black, 43% non-Hispanic White, 30% Hispanic, 3% Asian/Pacific Islander, and 2% other race/ethnicities), with a mean age of 46.8 (SD=14.8) and mean education of 13.7 years (SD=2.7). Independent samples t-tests were performed to investigate the differences in visual learning and memory abilities between the chronic pain and MNP groups.
Results:Chi-square analyses revealed significant differences between the pain and MNP groups on race, with more non-Hispanic White and Hispanic patients represented in the MNP group. There were also modest group differences in age and education. For the chronic pain group, patients scored lower on both BVMT-R Total T-Score (mean difference = 9.65T, p<.001) and BVMT Delayed Recall T-Score (mean difference = 8.97T, p<.001). The effect size was robust for both for Total T-Score (d = 0.682) and Delayed Recall T-Score (d = 0.632). In contrast, the difference in BVMT Recognition Discriminability was not statistically significant.
Conclusions:This study demonstrated significant differences in performance between mixed neuropsychiatric and chronic pain patients. Preliminary evidence indicated that chronic pain patients displayed lower visual mediated encoding and retrieval performance, although their recognition is comparable. Although the nature of this study was targeted toward visual learning and retrieval, it is likely that the known impact of chronic pain on attention, working memory, and processing speed accounts for this relationship. Future studies will benefit from further elucidating these potential mechanisms and better inform clinical decision-making and neuropsychological testing performance in patients with chronic pain.
