This paper undertakes an analysis and discussion of the methodological challenges and insights derived from three longitudinal qualitative studies, all conducted in Chile during the COVID-19 pandemic and subject to comprehensive theoretical-methodological reflection processes centred on their respective designs. This analysis makes a significant contribution to interdisciplinary discussions within social research, with a particular emphasis on longitudinal trajectories. First, we present a comparative analysis of three studies in social work, utilising Saldaña\'s questions addressing changes and learning in longitudinal studies. The first study explores the labour trajectories of researchers, the second focuses on the educational trajectories of students, and the last examines therapeutic alliance trajectories between social workers and families within the child protection system. Following this, we delve into the methodological decisions made by the research group during the execution of these longitudinal studies. This encompasses an examination of participant involvement, temporal definitions of the adopted designs, and the most suitable methodological tools for analysing change processes over time. The outcomes of this comparative analysis reveal the distinctive characteristics of the three longitudinal studies, providing insights into how the time dimension is explored within them. We highlight key criteria essential for consideration in longitudinal qualitative research, particularly regarding participants and methodology. In conclusion, we advocate for an expanded reflection within the realm of longitudinal qualitative methodology, encompassing aspects such as design choices, approaches to data analysis, integration of technology in information processing, and strategies for maintaining participant engagement.

BACKGROUND: Discontinuation of medications such as methadone and buprenorphine amongst patients receiving opioid agonist treatment (OAT) is an international phenomenon. Recent developments in OAT medication include depot-injections of buprenorphine. Circumstances underlying discontinuation of these new formulations of medication are not fully understood from a qualitative perspective.
METHODS: Data derive from a longitudinal qualitative study of patients\' experience of long-acting injectable buprenorphine (LAIB), involving semi-structured telephone-interviews held at six-points in time. The relevant dataset for this article consists of 44 interview transcripts, generated from 8 participants who were each affected by discontinuation of LAIB prescriptions (during the first 12-months of treatment). Analyses sought to identify circumstances associated with LAIB discontinuation and data were further situated within a framework of \'evidence making intervention\' and associated \'matters-of-concern\'. Matters-of-concern relate to the ways in which an intervention is \'made\' and constructed through engagement and practice, from the perspective of the recipient.
RESULTS: In this study, participants experienced either \'discontinuation of LAIB prescriptions by treatment services\' or patient-led \'opt-out\' from treatment. Matters-of-concern underlying the former were associated with late attendance for scheduled appointments, non-prescribed substance use or receiving a custodial sentence. Matters-of-concern relating to patient-initiated discontinuation were associated with personal circumstances that affected treatment motivation, side-effects (of buprenorphine), a preference to resume heroin use, or because individual treatment goals had been achieved.
CONCLUSIONS: The assorted matters-of-concern that influence discontinuation of LAIB demonstrate that such OAT is complex and multi-faceted, is neither fixed nor stable, and does not generate universally shared outcome. Experiences of LAIB discontinuation are shaped by a wide range of social, temporal and treatment-related effects that include disconnected therapeutic alliance between patient and treatment providers. In order to maximise the benefits of LAIB it is necessary to develop meaningful therapeutic alliances (notwithstanding policy boundaries) to enable exploration of matters-of-concern during treatment.

Problems with schools\' indoor-air quality are common, and they can cause health problems to adolescents. However, no previous research has examined how adolescents make sense of such contaminated socio-material environments or what kinds of agency those environments afford. Taking an ecological psychology perspective informed by frame analysis, we analysed longitudinal focus group interviews with adolescents in a Finnish school with longstanding indoor-air problems. We constructed three composite first-person narratives that reflected different experiential frames, with corresponding forms and changes of agency. We found that our adolescents made sense of the same socio-material environment and its affordances in very different ways, and this process afforded them to develop many kinds of agency that changed over time.

BACKGROUND: People who have communication difficulties may benefit from using augmentative and alternative communication (AAC). Understanding and measuring outcomes from the use of AAC is an important part of evaluating the impact of devices and services. Outcome measurement needs to reflect the changing nature of the impact of using AAC on an individual\'s ability to participate in activities of daily life. There is a limited understanding of the concepts that should inform the evaluation of outcomes from AAC device provision, nor how people\'s expectations from AAC may change over time.
OBJECTIVE: To inform the development of a patient-reported outcome measure for AAC by understanding more about people\'s expectations from AAC and how these change over time.
METHODS: A longitudinal qualitative research study was designed and carried out with seven participants over a period of 2 years. Participants were recruited from a regional specialist assessment service for AAC in the south-west of the UK. Four semi-structured interviews were carried out: (1) before assessment for AAC, (2) after assessment, (3) directly after provision of an AAC device and (4) between 6 and 12 months after provision. An original analytic method was used in this study that built on the principles of longitudinal interpretative phenomenology analysis, applied with a dialogic theoretical lens. This approach enabled the inclusion of a range of multimodal and embodied data collected to this study and allowed the research team to draw out salient themes across the cohort group while attending to the influence of time and context on experience.
RESULTS: The results confirm and extend the three core concepts that were used to guide analysis: changes; contexts; future possibilities. The contextual and temporal influences on outcomes attainable from AAC for this cohort were also identified and illustrated through cross-case comparison. Deeper, analytic, and conceptual engagement with theory, which was then applied to analysis of the data, provided methodological rigour in the study. The results enhance our understanding of people\'s hopes and expectations from AAC and how these change over time.
CONCLUSIONS: This qualitative longitudinal research study provides new insights into the journeys of people who experience communication disability, and the shifting nature of their sense of identity as they engage with, and learn from using, AAC. The study is significant as it attends to the dynamic nature of experience and how contextual and experiential factors influence people\'s hopes and expectations from AAC. The paper presents an original application of longitudinal qualitative research methodology with people who use AAC which can be further applied and tested in the field of communication disability research.
CONCLUSIONS: What is already known on this subject We did not know the impact that time has on the concepts that have been identified to represent important outcomes from AAC. The existing concepts used to define outcomes from AAC were not adequately conceptualized to develop a patient-reported outcome measure. This study sought to extend our knowledge about outcomes from AAC. What this paper adds to the existing knowledge This study adds to the methodological toolkit available for qualitative inquiry in the field of communication disability research by presenting a longitudinal qualitative research methodology. It adds depth to our understanding of the concepts that underpin outcomes from AAC and highlights the dynamic nature of contexts and how this influences desired outcomes. What are the potential or actual clinical implications of this work? This longitudinal qualitative research study provides a broader perspective on the experience of getting AAC. It will enable clinicians to better navigate the contextual and transitionary factors that influence people\'s experience of acquiring AAC devices. The enhanced concepts described will also support clinical conversations that consider the wider facets of communication and what AAC can add to existing communicative tool kits beyond getting a message across.

BACKGROUND: Conceptualisations of the \'patient journey\' are popular within health service research. Patient journeys provide a person-centred approach to health care that typically prioritise subjective patient experience with the aim of improving relevant forms of intervention. This article explores the conceptualisation of retention in treatment for opioid use disorder (OUD) using long-acting injectable buprenorphine (LAIB) as a journey.
METHODS: Data derive from a longitudinal qualitative study, involving semi-structured interviews (held at six time-points), with participants who each initiated LAIB for the first time. Data analysis for this article focuses exclusively upon the experiences of those who had continued with LAIB treatment throughout one year (11 participants). Framework and thematic narrative analyses of 64 interviews with 11 participants sought to identify \'retention-narratives\' that would indicate a \'retention journey\' associated with LAIB treatment.
RESULTS: Shared treatment experiences consisted of three distinct phases (Withdrawal and Separation, Transformation, and Engagement) that progressed in a linear and intersecting manner through time. Each phase had features that defined treatment experiences at a given time but changed as treatment progressed. All 11 participants experienced multiple features within each of the three treatment phases and all participants reported separation from their respective service provider throughout the first 12 months of treatment. Although some valued the latter separation, most were dissatisfied by reduced levels of contact.
CONCLUSIONS: Retention in treatment for OUD with LAIB, for at least 12-months, can be conceptualised as a journey. This conceptualisation emphasises the benefits (and challenges) clinicians and patients may expect to encounter during the first year of a LAIB treatment programme. An added implication of conceptualising LAIB treatment in this manner is that optimal benefits of the medication (as observed by participants) began to emerge during \'months 7-12\' of the retention journey.

Background: Non-prescribed substance use (NPSU) during the treatment of opioid use disorder (OUD) is a recognized phenomenon. The use of non-prescribed substances is associated with discontinuing treatment and drop-out can occur within the early weeks of treatment, before benefit from treatment occurs. Recent developments in treatment include long-acting, slow-release depot buprenorphine injections. This article focuses on NPSU during the first month of treatment with depot buprenorphine, addressing the frequency with which it occurs, the substances used, and reasons for use. Methods: 70 semi-structured interviews (held at three time-points) were conducted with 26 patients initiating depot buprenorphine as part of a longitudinal qualitative study. Analysis prioritized content and framework analyses. Findings: 17/26 participants self-reported NPSU at various times during the first month of treatment. NPSU typically involved heroin, crack-cocaine and some use of benzodiazepines and/or cannabis. Participants\' reasons for heroin use were connected to their subjective accounts of opioid withdrawal symptoms, the management of pain, and experimentation (to test the blockade effect of buprenorphine). Frequency of heroin use was typically episodic rather than sustained. Participants associated crack-cocaine use with stimulant-craving and social connections, and considered their use of this substance to be difficult to manage. Conclusions: Patients\' initial engagement with treatment for OUD is rarely examined in qualitative research. This study highlights how NPSU amongst patients receiving new forms of such treatment continues to be a challenge. As such, shared decision-making (between providers and patients) regarding treatment goals and NPSU should be central to the delivery of depot buprenorphine treatment programmes.

Working mothers face challenges in pursuing their career aspirations due to work-family conflict. The recent COVID-19 pandemic has posed added challenges for working mothers by increasing care demands while also causing numerous health, economic and social disruptions. In this paper, we examine the impact of COVID-19 on Korean working mothers\' career aspirations. We employ a longitudinal qualitative design by analysing 64 in-depth interviews with 32 mothers of young children in South Korea. By interviewing the same women before (2019) and during the COVID-19 pandemic (2020), we are able to document how working mothers\' career aspirations were impacted by COVID-19. Findings show that all working mothers in the sample experienced increased care demands due to COVID-19. However, the influence of COVID-19 on working mothers\' career aspirations hinged on gendered beliefs related to childcare responsibility. When working mothers believed or were subjected to beliefs that mothers should be the primary caregiver for children (gendered care belief), their career aspirations were tempered or relinquished. On the other hand, those who believed that mothers should not be held solely responsible for childcare (gender egalitarian care belief) continued to pursue their career aspirations or experienced career advancements during COVID-19. Findings suggest that beliefs related to care responsibilities play an important role in working mothers\' pursuit of their career aspirations, and potentially their future careers.

This study presents descriptions of epistemic injustice in the experiences of women medical students and provides accounts about how these students worked to redress these injustices. Epistemic injustice is both the immediate discrediting of an individual\'s knowledge based on their social identity and the act of persistently ignoring possibilities for other ways of knowing. Using critical narrative interviews and personal reflections over an eight-month period, 22 women students during their first year of medical school described instances when their knowledge and experience was discredited and ignored, then the ways they enacted agency to redress these injustices. Participants described three distinct ways they worked to redress injustices: reclaiming why they belong in medicine, speaking up and calling out the curriculum, and uplifting one another. This study has implications for recognizing medical students as whole individuals with lived histories and experiences and advocates for recognizing medical students\' perspectives as valuable sources of knowledge.

UNASSIGNED: Patient and public involvement (PPI) is becoming more common in research, but has been problematized for lack of diversity. While PPI literature increasingly focuses on assessment of PPI on research, a focus on the contributors is less common. This study tracked the experiences of involvement among four refugee parents involved as public contributors in a child mental health trial, over three years.
UNASSIGNED: The study used a longitudinal qualitative design with focus group discussions. Data were analysed using thematic analysis combined with a longitudinal analysis approach.
UNASSIGNED: The refugee parents\' motivations for being involved changed from focusing on individual benefits to societal change. They initially viewed themselves as guests, which transformed into utilizing the group for social support. Time impacted trust-building positively, with continued collaboration strengthening trust. Practical aspects were dominant in the beginning, which shifted over time to allow more focus on research. They identified several learnings they gained from involvement. A discrepancy in how parents and researchers viewed involvement was identified, where parents saw researchers as owners of the research.
UNASSIGNED: To sustain successful PPI collaboration over time, researchers need to prioritize investment in time and resources, in communication, including working with interpreters, and in continued adjustments.

The growing body of information-seeking and decision-making literature in motor neurone disease (MND) has not yet explored the impact of health literacy. Health literacy relates to the skills people have to access, understand, and use health information and is influenced by motivation to engage with healthcare. We aimed to better understand how people affected by MND engage in healthcare by examining longitudinal interview data using the construct of health literacy. Semi-structured interviews were conducted with 19 persons living with MND and 15 carers recruited from a specialist MND clinic using maximum variation sampling. Transcripts were deductively coded using a framework of health literacy behaviours. The analysis used a matrix-based approach for thematic analysis of longitudinal data. People living with MND and carers sought nuanced information dependent on their priorities and attitudes. Information uptake was influenced by perceived relevancy and changed over time. Time allowed opportunity to reflect on and understand the significance of information provided. The findings indicate that persons living with MND and carers benefit when information and consultations are adapted to meet their communication needs. The results highlight the potential benefits of gaining an early understanding of and accommodating the communication needs, personal preferences, and emotional readiness for information for persons living with MND and their carers.
