Dual language learners, or DLLs, are children who are developing proficiency in two languages simultaneously, typically a home language and English. According to demographic data cited by the researchers, this population in the United States is growing rapidly and becoming increasingly linguistically diverse. Yet the vast majority of intervention studies have focused almost exclusively on Spanish-English bilingual children. That narrow focus has left educators with little rigorous evidence to guide their work with children from other linguistic communities, including the growing number of South Asian language speakers in American preschools.

The research team, led by Ekta Ghosh of the University of Denver together with Rashida Banerjee, Caroline James, and Dina Malala, set out to address this gap directly. Their question was deceptively straightforward: does dialogic reading work for Bengali-speaking preschool DLLs who are at risk of developmental delay? The answer, based on their single-case research design, appears to be a cautious but encouraging yes. Across all three participants, the intervention produced measurable improvements in both English and Bengali vocabulary, in alphabetic knowledge, and in behavioral engagement during literacy activities.

Dialogic reading itself is not a new idea. First developed by researchers Whitehurst and colleagues in the 1990s, the technique transforms shared book reading from a passive experience into an active dialogue. Rather than simply reading the words on the page aloud, the adult prompts the child with questions, expands on the child’s responses, provides feedback, and gradually shifts more of the storytelling responsibility to the child. The method follows a progression from simple completion and recall prompts to open-ended questions and wh-questions, encouraging children to become active narrators of the story rather than passive listeners.

The theoretical appeal of dialogic reading for dual language learners lies in its flexibility. Because the technique relies on conversation rather than scripted instruction, it can be adapted to a child’s existing language resources. Children can respond in either language, and adults can scaffold meaning across both. This aligns with broader theoretical frameworks in bilingual education, including the concept of translanguaging, which treats a child’s full linguistic repertoire as a resource for learning rather than a barrier to it. It also connects to decades of evidence that a strong home language foundation supports, rather than hinders, second language acquisition.

Methodologically, the study employed a single-case research design, an approach well suited to intervention research with small, specific populations. Single-case designs involve repeated, systematic measurement of each participant’s performance during a baseline phase and an intervention phase, allowing researchers to demonstrate experimental control at the level of the individual child. The approach follows established design standards articulated by Kratochwill and colleagues, and it is particularly valuable when random assignment to large treatment and control groups is impractical, as is often the case with linguistically specific populations of young children.

The participants were three Bengali-speaking preschoolers, aged 36 to 60 months, who were developing proficiency in both English and their home language and who had been identified as at risk of developmental delay. The researchers measured a battery of outcomes, including expressive and receptive vocabulary in both languages, lowercase and uppercase letter identification, letter-sound knowledge, and sight word recognition. They also tracked behavioral engagement, observing how actively each child participated in literacy activities. Screening with the Clinical Evaluation of Language Fundamentals, Fifth Edition, helped document the children’s language profiles at the outset.

The results, presented in detailed graphs tracking each child’s performance across baseline and intervention sessions, showed improvements on every outcome measure for every participant. Vocabulary responses increased, letter identification and letter-sound knowledge improved, and the children showed higher levels of positive engagement alongside reductions in off-task and disengaged behaviors during the intervention phase. The engagement findings are particularly noteworthy, because behavioral engagement is both a consequence of effective instruction and a driver of future learning. Children who are absorbed in a book activity practice more language, attend more closely, and build stronger associations with literacy itself.

Why does this matter beyond the classroom? Early language and literacy skills are among the strongest predictors of later academic achievement, and national assessment data have long shown persistent reading performance gaps. Children who enter school with underdeveloped vocabulary and emergent literacy skills face an uphill climb that tends to widen over time. For dual language learners at risk of developmental delay, the stakes are even higher, since early delays can compound across domains. Interventions that are inexpensive, scalable, and adaptable to diverse home languages, as dialogic reading is, therefore carry enormous practical significance for early childhood educators and families alike.

The study also contributes to a growing international evidence base. Recent systematic reviews and meta-analyses have found that shared picture book reading interventions support child language development broadly, and randomized trials in Scandinavia have examined dialogic reading with additional language learners in preschool settings. Other recent work has tested culturally adapted, caregiver-mediated versions of early literacy interventions within community organizations serving Latino families. What the new study adds is evidence from a linguistic community that has been nearly invisible in this literature, extending the reach of the technique beyond the Spanish-English populations that have dominated United States research.

The authors are careful to frame their findings as preliminary. With three participants and a single-case design, the study cannot establish how large the effects are on average or how they generalize to other children and settings. Single-case research answers questions about whether an intervention can work for individuals under specified conditions, not whether it will work everywhere. The researchers themselves describe the results as preliminary evidence supporting culturally responsive early literacy practices for preschool DLLs from underrepresented linguistic communities, a formulation that invites replication rather than claiming definitive proof.

Even so, the implications for practice are concrete. Preschool teachers, paraprofessionals, and families can be trained to implement dialogic reading with relatively modest resources, and prior studies have shown that even paraprofessionals can deliver the technique effectively when properly coached. The key ingredients are prompting, expansion, feedback, and repetition, all delivered within the warmth of a shared reading experience. For educators serving children from South Asian language backgrounds, the study suggests that these techniques can honor the home language while building English skills, rather than forcing a choice between the two.

There is also a broader equity argument embedded in this research. As the United States becomes what demographers have called superdiverse, with young dual language learners speaking an ever-widening array of home languages, intervention research that samples only one or two linguistic groups risks leaving entire communities without evidence-based guidance. Studies like this one, small in scale but methodologically rigorous, begin to correct that imbalance. They demonstrate that the tools of early literacy science can travel across languages and cultures when researchers take the trouble to test them there.

The road ahead involves larger studies, longer follow-up periods to test whether gains persist, and exploration of how dialogic reading interacts with classroom curricula and family practices. But the core message of the study is already resonant: a conversation over a picture book, conducted with intention and skill, can help a bilingual preschooler at risk of delay find their words in two languages. In a field often dominated by debates over technology and curriculum, that is a refreshingly human finding, and one that any parent or teacher can put into practice at bedtime tonight.

The study employed a qualitative descriptive design, a methodology suited to capturing the lived experience of professionals navigating the transition from student to practitioner. Thirteen occupational therapists participated in semi-structured interviews, a sample size consistent with the norms of qualitative inquiry, where depth of insight matters more than statistical generalizability. The interviews were audio-recorded and transcribed verbatim, then analysed using Braun and Clarke’s reflexive thematic analysis, a widely used approach that involves systematic coding of transcript data and the iterative development of themes that capture patterns of meaning across participant accounts. The researchers used NVivo 15, a dedicated qualitative data analysis software package, to manage and organize the coding process.

Trustworthiness, the qualitative equivalent of validity, was addressed through several established techniques. The authors describe the use of reflexivity, in which researchers critically examine how their own backgrounds and assumptions might shape the interpretation of data. Peer debriefing allowed colleagues to challenge and refine emerging interpretations, while triangulation helped ensure that findings were anchored in multiple perspectives within the dataset. The maintenance of an audit trail, a documented record of analytical decisions from raw transcript to final theme, further strengthens confidence in the study’s conclusions. Ethical clearance was granted by the University of the Witwatersrand Human Research Ethics Committee under clearance number H24/03/29, and all participants provided written informed consent before data collection began.

From the analysis, three major themes emerged. The first concerns the genuine strengths of the mental health curriculum as currently taught in South African occupational therapy programmes. Participants identified expert teaching as a foundation of their learning, praising the knowledge and clinical experience of academic staff who delivered the mental health content. They also highlighted meaningful undergraduate clinical supervision, describing placements in which experienced clinicians guided their developing skills in real-world settings. Multidisciplinary learning experiences, in which students trained alongside future doctors, nurses, psychologists and social workers, were credited with building an understanding of how mental health care functions as a team endeavour. Taken together, these elements gave many participants a sense that their education had, in important respects, prepared them for the demands of mental health practice.

The second theme, however, reveals significant gaps between what the curriculum delivers and what the realities of practice demand. Participants reported limited preparation for culturally responsive practice, a shortfall with particular weight in South Africa, where therapists routinely serve clients whose languages, belief systems and cultural frameworks around mental illness differ markedly from their own. Without explicit training in how to adapt assessment and intervention to diverse cultural contexts, graduates described uncertainty about whether their therapeutic approaches were appropriate or effective for the communities they served. This gap is not merely academic; in mental health care, where trust and communication are central to outcomes, cultural misalignment can undermine treatment adherence and therapeutic relationships.

Participants also described feeling underprepared for complex mental health presentations. Undergraduate training, they indicated, did not always expose them to the severity, acuity or diagnostic diversity of the cases they encountered once qualified. Clients with co-occurring psychiatric and physical conditions, acute crises, or severe and persistent mental illness presented challenges that exceeded the scenarios they had practised as students. Related to this was a third shortcoming: limited confidence in applying occupational therapy interventions specifically within mental health contexts. Occupational therapy in psychiatry involves distinct techniques, from activity-based rehabilitation to vocational and social skills training, and participants suggested that the translation of general occupational therapy principles into mental health settings had not been sufficiently rehearsed during their studies.

The third theme captures the participants’ own recommendations for reform, and these form perhaps the most actionable part of the study. Graduates called for expanded community-based mental health training, arguing that learning within the communities where clients actually live would build the contextual competence that hospital-based placements cannot fully provide. Community-based education has gained traction globally as a strategy for aligning health professional training with population needs, and the participants’ experiences suggest that South African occupational therapy programmes could benefit from deepening this component. They further recommended integrating physical and mental health teaching throughout the curriculum, rather than treating them as separate streams, reflecting the growing recognition that the two domains are inseparable in real clinical populations.

The recommendations also extended to the structure and consistency of training itself. Participants urged improved supervision and feedback during clinical placements, emphasizing that the quality of guidance received as a student shapes confidence as a practitioner. Inconsistent experiences across undergraduate mental health curricula emerged as another concern, with graduates from different training pathways describing markedly different levels of exposure to mental health content. Greater standardization, or at minimum greater alignment, across programmes could help ensure that all newly qualified occupational therapists enter the workforce with a comparable baseline of mental health competence. The authors conclude that undergraduate occupational therapy education in South Africa provides an important foundation for mental health practice, but that it could be strengthened through greater cultural responsiveness, expanded community-based learning, improved supervision and feedback, and greater curricular consistency.

The significance of these findings extends beyond occupational therapy. In resource-constrained health systems, newly qualified professionals are frequently the backbone of service delivery, and South Africa’s persistent shortages of mental health specialists mean that occupational therapists often fill roles that would, in better-resourced settings, be staffed by more experienced clinicians. The transition from student to practitioner is a well-documented period of vulnerability, marked by reality shock, reduced confidence and, in some cases, early attrition from the profession. When that transition occurs with limited supervision, as the study’s background notes, the stakes for both clinician wellbeing and patient safety rise considerably. Understanding precisely where educational preparation falls short is therefore a prerequisite for designing interventions that protect the workforce and the populations it serves.

The study, published on 6 October 2026 as an open access article, was supported in part by the Female Academic Leadership Fellowship, which allowed the first author to dedicate time to the conception, data collection and writing of the research. The authors declare no competing interests. While the qualitative design means the findings describe the experiences of thirteen therapists rather than measuring preparedness across the entire profession, the consistency of the themes and the methodological safeguards employed lend weight to the conclusions. For educators, the message is clear: the foundations are sound, but the gaps in cultural training, exposure to complexity and community-based practice are real and fixable. For the graduates themselves, the study offers validation that their struggles reflect systemic curriculum limitations rather than personal inadequacy, and a roadmap for the reforms that could make the next generation of South African mental health practitioners better equipped for the work awaiting them.
