ABSTRACT
Older forensic psychiatric patients (defined as aged 50 or over) have complex
needs and require specialized treatment to enable recovery and reduce risk.
Little is known about what service provision is available for this population, so
a scoping literature review was undertaken to establish the extent of service
provision and if services are specifically modified or designed for this popula
tion. The literature was searched through academic journal databases and
Google Scholar, and outputs were screened for suitability and assessed for
quality. Eight studies (four qualitative, four quantitative) were included in the
review. Studies were mixed in terms of methodological quality, and with several
limitations. Qualitative data provided perceptions regarding positive (e.g., suffi
cient types of therapy) and negative (e.g., lack of age-appropriate services)
aspects of interventions. Quantitative data were descriptive, focusing mainly
on identifying provision available (e.g., art therapy, violence reduction) and
where needs were not being met (e.g., physical needs, education). Results
indicate little provision in place adapted specifically for older forensic psychia
tric patients. Findings highlight the need for further research to understand and
effectively implement interventions and service provision for older forensic
mental health patients to ensure practice is evidence based.
Introduction
The world’s population is aging, and governments need to design innovative
policies and public services specifically targeted to older persons, including
policies addressing healthcare (United Nations, Department of Economic and
Social Affairs, Population Division, 2019). This aging population means a growth
in older people requiring mental health support, including forensic mental health
service provision. In the UK and other Western countries around 20% of secure
patients are over 50 (Di Lorito et al., 2017; Di Lorito et al., 2018; 2017), and this
proportion is likely to grow as people live longer (Coid et al., 2002; Lewis et al.,
2006; Di Lorito, Völlm et al., 2019). Due to common histories that include poor
health management and substance abuse, many people with long-term mental
health disorders also experience the challenges associated with old age earlier
and have significantly reduced life expectancy (15–20 years) (Chesney et al.,
2014). It is necessary that there is adequate and appropriate service provision
for this population.
Over the past 20 years, there has been an increase in demand for forensic
mental health services across many countries, a trend that comes at significant
human resource and economic cost (Jansman-Hart et al., 2011). Forensic men
tal health patients, defined broadly as those who are ‘both mentally disordered
and whose behavior has led, or could lead to offending’ (Mullen, 2000, p. 307),
sit in a complex intersection of health, social care, and criminal justice systems.
Specific service provisions are required for forensic mental health patients,
including secure hospital units (low, medium and high security) and commu
nity services. Mental health services need an integrated approach, combining
geriatric old age psychiatry and generic forensic psychiatry services, as older
offenders with mental health difficulties sit within criminal justice, forensic
psychiatry and psychology, and old-age psychiatric services (Curtice et al.,
2003), which as stand-alone services and not integrated ones, struggle to
manage this group of patients (Shah, 2006).
Forensic psychiatric patients present with unique mental, physical and
social care needs, and these are likely to differ from younger patients due
to ageing-related factors (Di Lorito, Völlm et al., 2019). Entrenched mental
illness is a feature for older patients, and they are more likely to be diagnosed
with more serious mental illnesses compared to younger offenders (Fazel &
Grann, 2002). It has been found that psychotic illnesses including schizophre
nia, schizotypal, delusional disorder and personality disorder are prevalent in
older forensic adults (Yorston & Taylor, 2009), as are dementia and
Alzheimer’s (Paradis et al., 2000). Many older forensic adults experience
comorbid mental health, substance use issues and have histories of trauma
(e.g., childhood neglect and abuse, violence) (Haugebrook et al., 2010; Maschi
et al., 2011). Older forensic psychiatric patients are also more likely to present
with increased rates of co-morbid physical health issues such as sensory
impairment (hearing and eyesight) (Lightbody et al., 2010), cardiac disease,
hypertension and diabetes (Paradis et al., 2000), as well as mobility problems
and issues (Coid et al., 2002). Older patients experience longer, more severe
and/or interrupted episodes of care, all of which impact their presentation,
needs and care requirements. These factors mean that the population of
older forensic patients are likely to require more and different specialist
interventions, activities, treatment and support than those required by
THE JOURNAL OF FORENSIC PSYCHIATRY & PSYCHOLOGY 3
qualitative methods and the few statistical analyses undertaken could not be
synthesised. This therefore limits the generalizability. They concluded the
knowledge base in this area needs building, perhaps through empirically
adapting interventions that have worked for older adults in the community,
followed by testing in correctional services. The focus of this paper’s review
will establish what is available specifically for older forensic mental health
patients in secure units and the community.
Older forensic patients have been described as ignored, misunderstood, and
poorly served (Yorston, 1999). There is a clear need for forensic mental health
services for older people, as the epidemiology, criminological, and clinical
characteristics of older people are sufficiently different to their younger coun
terparts (Natarajan & Mulvana, 2017). Research has suggested that for older
adults with serious mental illness, interventions need adapting and developing
to be more individually based to meet specific requirements (Forsman et al.,
2011). However, there is no clear understanding of what provision is currently
provided that is specifically for older forensic mental health patients, what is
missing and if this is appropriate and suitable for this population. This under
standing is valuable to patients, clinicians, commissioners, The National
Institute for Health and Care Excellence (NICE) and policy makers and ultimately
for being able to establish intervention effectiveness. Therefore, the aim of this
review is to assess what service provision for older forensic mental health
patients is currently offered, specifically addressing the research question:
What interventions and therapies have been designed for older forensic mental
health patients, residing as inpatients in secure hospitals or in the community?
Method
Based on the research question, study inclusion and exclusion criteria were
developed to identify older adults (age ≥ 50 years), forensic mental health
patients (inpatients [low, medium or high security] or in the community), who
had experienced intervention provision. Inclusion criteria comprised: i) the
article described an intervention; (ii) the intervention was for patients in
a secure mental health unit or the community; (iii) the population were forensic
mental health patients; (iv) the population were age ≥ 50 years (male or female);
and v) articles were written in English. Exclusion included: i) articles with no
intervention provision identified; (ii) prison populations, offenders awaiting
sentence, prisoners held in temporary incarceration; (iii) studies on general
mental health populations; iv) the population were age < 50 years and/or all
age ranges were examined as one group; and v) articles not written in English.

Search strategy
Initially, a search of academic databases was completed. Table 1, presents the
terms and databases used for this initial search.
Where available a thesaurus search was used for the target and the inter
vention using the terms psychiatry and psychotherapy. A further search strat
egy was then implemented, using the search terms [6–8] AND [10–12], but with
age limits applied as a filter to the searches. See Table 1 for the appropriate
filters utilized for each database search.
To extend the reach, Google scholar was searched, using the following terms
(older OR elderly) AND (‘forensic mental health’ OR ‘forensic patient’) AND
(intervention OR treatment OR therapy). This search returned 8900 articles,
and so the first 300 were screened as recommended by Haddaway et al. (2015).
Finally a hand search of the references was also implemented, and poten
tially relevant articles were identified, located and screened.
Articles were selected following a multi-step process as advocated by
Moher et al. (2009) in their guidelines for conducting and reporting systema
tic reviews. Figure 1 outlines the process followed.
Initially, manuscripts identified through database searches and Google Scholar
were exported to RefWorks, where duplicates were removed. Titles and abstracts
were reviewed simultaneously. When titles were assessed articles were retained if:
(1) the title implied there was an intervention; (2) the population were forensic
mental health; (3) the population were identified as older/ageing; (4) it was
unclear based solely on the title if the article was relevant or not; and (5) more
information was required from an abstract read to determine if inclusion/exclu
sion criteria had been met. Following a review of the abstracts, articles were

retained if: (1) the abstract included information that suggested the inclusion
criteria had been met; and (2) it was still unclear if the study was relevant for the
review or not. Finally, full texts were read and reviewed, and relevant articles were
identified and selected.
Analysis
Quality of empirical papers was assessed using the Mixed Methods Appraisal
Tool (MMAT) Version 2018 (Hong et al., 2018). The MMAT is used to provide
a detailed presentation of the ratings of each criterion that it assesses and not
an overall score by each article (Hong et al., 2018). For all the qualitative
articles, the qualitative approach was appropriate to answer the research
questions posed. The methods used across all the studies were adequate in
regard to the method of data collection (e.g., in depth interviews and/or
group interviews, and/or observations) and the form of the data (e.g., tape
THE JOURNAL OF FORENSIC PSYCHIATRY & PSYCHOLOGY 7
recording, and/or field notes). Three studies were solely reliant on one form,
e.g., interviews (Di Lorito et al., 2018; De Smet et al., 2015) or focus groups (Di
Lorito, Dening et al., 2019), although Visser et al. (2019) utilized observational
field-notes alongside interview data. All of the qualitative articles commented
on the use of multiple coders for the data analysis for accuracy; however, only
one (De Smet et al., 2015) formally assessed and reported inter-rater relia
bility, finding a Cohen’s kappa score of 0.72 and a degree of agreement of
97.2%, which is considered as substantial. Based on the methodologies used
the findings were adequately derived from the data, although it was unclear
across the studies the epistemological position taken, and some of the
studies (e.g., Di Lorito, Dening et al., 2019) lacked information about the
process of analysis, making it difficult to make a judgement about this
criterion. However, across all studies the participant quotes utilized sup
ported the themes well.
The quantitative papers were descriptive and relevant analysis not always
the main focus of the research. Of the articles, Di Lorito, Völlm et al.’s (2019)
paper was the strongest of those reviewed in relation to the MMAT criteria. In
the case of the other three, very little information was given about the
methodological approach taken. For all the papers the sampling was ade
quate (non-probability), although probability sampling would have strength
ened the research, and there was limited information about sampling
particularly in three of the articles (Das et al., 2011, 2012; Shah, 2006). It is
not apparent across all of the papers if the sample were representative of the
target population, as there is no clear description of the target population or
of the sample, such as respective sizes, inclusion and exclusion criteria and
reasons why certain eligible individuals chose not to participate. The mea
sures and psychometrics selected were appropriate across the articles,
although there is no reporting of validity or reliability tests, neither those
associated with the measures generally nor those measured specifically for
the samples in the four papers. Information about response bias was sparse
and therefore it was difficult to assess the quality of this within the papers.
Analysis was described in the work by Di Lorito, Völlm et al. (2019), but there
was inadequate detail in the other three papers to make a full assessment
regarding this criterion.
Results
Following review of 176 full text articles, 8 studies were identified as relevant
to include. The articles found and included are described and summarized in

into the phenomenon. The majority of the articles were deemed not relevant
because they either did not focus on older populations or did not include
forensic mental health service users. Findings from a synthesis of the quali
tative research will be presented first, followed by an examination of quanti
tative research.
Qualitative Research
Due to the fragmented nature of the research and lack of data, synthesis of
the qualitative research only enabled the identification of two broad themes
to encapsulate the key observations: ‘positive perceptions of service provision’
and ‘negative perceptions of service provision’.
a thematic analysis of interview data and observational notes from service users
(11 males, 4 women) aged 50–71 and over and residing in low and medium
secure units, identified the theme of ‘Participation in activities’, where it was
observed weekly routine activities were important, as was the occupational
therapy program. They found most activities provided in the unit were age
inclusive, although some attracted predominantly younger participants; how
ever, it was not disclosed why this was the case.
Finally, a factor identified in the review as a positive from the research by
Di Lorito et al. (2018) related to physical health conditions. From service users’
perspectives it was felt these were addressed well (from a medical point of
view), and perhaps better than would be in the community, with access to
consultations widely available. However, this was not mirrored across all
studies as, beyond medical intervention, not all service users felt their physi
cal needs were addressed or catered for (e.g., Visser et al., 2019).
noted secure units did not offer age-specific forensic services, a gap in service
provision for this population.
Di Lorito, Dening et al. (2019) examined the views of members of staff who
had worked with older patients in forensic settings with an aim of establish
ing how well services met the needs of this population. Data were collected
through focus group research with different members of staff, e.g., nurses,
consultant psychiatrists, occupational therapists (across high and low security
units). One of the themes found was ‘Addressing patients’ needs’, which
encapsulated views about barriers to addressing needs and service provision
and improvement. In relation to interventions, a barrier and negative factor
identified was an ability to offer activities suitable for older patients, particu
larly for longer stay patients who lacked stimulation, a finding mirrored in
service user’s views (e.g., Di Lorito et al., 2018; De Smet et al., 2015; Visser
et al., 2019). In addition, it was suggested a lack of available resource –
financial and staffing – meant specific interventions for older people were
neglected and unlikely to be implemented.
Another negative perception found related to physical health, which
becomes more problematic as people age. Visser et al. (2019) highlighted
that some of the older patients were unable to attend certain interventions
because their physical health prevented them from doing so. The majority of
their participants had extensive physical health issues and staff intervention
in relation to this was generally inadequate (although positive when inter
vention was with primary care practitioners). Along a similar line, Di Lorito
et al. (2018) found some participants reported issues with inaccessibility for
some interventions due to mobility problems that come with aging and
poorer physical health. Whilst physical activity was seen as positive, it was
noted gym equipment was not always suitable for older patients, i.e., weights
were too heavy.
In summary, patients and staff presented both positive and negative
perceptions about the service provision for older forensic mental health
patients, although some of the findings were contradictory across studies.
Positive narrative related to quality, type and suitability of activities available
in both secure settings and the community, specific provisions for those over
50, psychosocial services, and medical treatment for physical health issues.
However, negative perceptions included narratives about: (i) boredom with
and uselessness of interventions; (ii) inappropriate therapies/lack of age-
appropriate interventions; (iii) poor quality of psychological support; and
(iv) lack of provision for those with poorer physical health.
Quantitative research
Quantitative research was sparse and less comprehensive than the quali
tative research identified. Only a handful of studies present elements of

data regarding this, and generally this was descriptive and not the main
focus of the research. No research has been undertaken specifically collat
ing an evidence base for service provision and intervention development
or delivery or evaluations of interventions for this age group. Due to the
fragmented nature of the research found, it is not possible to synthesize
findings, so each article and main findings are presented separately.
Di Lorito, Völlm et al. (2019) undertook some quantitative analysis, and
although the main analysis focused on characteristics, a small part examined
the types of interventions older forensic mental health patients receive in
low, medium and high secure settings. The total study sample was 93;
however, the analysis that examined interventions comprised a subsample
of 41 patients (44% of the total population aged ≥ 50 years), of whom only
three were female. The authors reported descriptive data on how many
participants had experienced different types of interventions, finding skills
development, n = 30 (72.2%); mental health awareness/psychoeducation,
n = 12 (29.3%); art therapy, n = 8 (19.5%); healthy lifestyle training, n = 8
(19.5%); dialectical behavior therapy, n = 7 (17.1%); substance misuse treat
ment, n = 7 (17.1%); music/dance therapy, n = 6 (14.6%); violence reduction
n = 6 (14.6%); and preparation for therapy/motivational work, n = 6 (14.6%).
Results also revealed their needs were met in 12 areas of daily living on
average (SD 3.5), with one of these including ‘treatment’ (n = 30; 74%).
However, 4 areas of needs were unmet, on average (SD 3.0) and one of
these was ‘daytime activities’ (n = 14; 34%). Patients were split into two
subgroups: <55 years old (n = 20) and ≥50 years (n = 21), and it was found
those below 55 years had significantly more unmet needs than those above
although this was not examined by individual categories.
This research offers some descriptives of, and a contextual understanding
into, the types of interventions offered and experienced by those over 50.
Beyond this, the data doesn’t offer any further information on this, such as
how appropriate/suitable interventions were, or about engagement, comple
tion, or outcomes. However, this was not the main aim focus of this part of the
study. This research allows a basic insight into what is being experienced,
although the data collected doesn’t support generalizability of findings.
Shah (2006) undertook an exploratory audit examining demographic,
clinical features, management advice and appropriateness of referrals to
a consultation-only old-age psychiatry liaison service for inpatients in med
ium and high secure forensic units. The consultant had one dedicated session
per week for older patients (defined as 60 years and over and younger
patients with dementia). The age range of the participants was 58–87 and
comprised 10 males and 1 female. Basic descriptive data were used, and part
of the audit involved noting the amount and different types of intervention
advice given. The intervention advice included medical (drugs and medica
tion, scans, x-rays and investigative procedures) but also referral for
THE JOURNAL OF FORENSIC PSYCHIATRY & PSYCHOLOGY 15
the CANFOR-S more of the younger patients had unmet needs for daytime
activity and education compared to older patients. However, this was as rated
by staff and not patients. Overall, when total needs were compared, signifi
cantly more younger patients had met needs than the older patients. There
was a significant unmet need for the older patients in relation to their
physical needs, and it was suggested these are complex and may change
over time and so careful consideration about these factors is required when
planning intervention, placement and care.
Overall, the quantitative evidence found is only descriptive data in nature,
from small numbers of participants. The evidence presented is therefore not
strong and robust. As such this provides evidence there are large gaps in the
literature and our knowledge base about service provision for older forensic
mental health patients in secure units and the community.
Limitations
In relation to the qualitative research presented, the data analysis offers the
opportunity to gather rich data and achieve an in-depth insight into
a phenomenon. However, it comes with limitations. De Smet et al. (2015)
acknowledge their findings are drawn from a small sample and so are not
conclusive. In addition to this acknowledgement, the sample was also diluted
further by comparing three different sites and through drop-out and selec
tion bias. Likewise findings from the other studies need to be viewed as
preliminary and contextualized within limitations including confirmation bias
(Di Lorito, Dening et al., 2019), sampling bias (for example, specifically there
was only 54% participation rate achieved by Visser et al., 2019), and lack of
representation (range of professionals’ views captured, lack of female service
users, different ethnicities and/or range of different units/trusts). It could be
argued those who declined, dropped out or were unable to take part in the
research are perhaps more important to understand. For example, those not
captured by Visser et al. (2019) were identified as more withdrawn from
activities and who spent more time in their room and their narratives about
this would have likely given a very different viewpoint and insight in compar
ison to those included in the study. This would suggest the scope of this type
of research needs widening, to involve a more diverse sample and examine
the context within which they reside.
As a general observation, no research had explicitly quantitatively examined
interventions for older mental health forensic patients, either in relation to
evaluations, intervention design and development or outcome studies. Of the
studies that examined interventions in some form, the findings were descriptive
rather than detailed statistical analysis of the data. The results expose some of the
different interventions experienced by older forensic mental health patients, with
no research examining the effectiveness or appropriateness of the interventions.
THE JOURNAL OF FORENSIC PSYCHIATRY & PSYCHOLOGY 17
The studies comprised relatively small samples, i.e. n = 41 (Di Lorito, Völlm et al.,
2019), n = 11 (Shah, 2006), n = 30 (Das et al., 2011, 2012), which limits the
statistical analysis, and does not afford generalizability. Both Shah (2006) and Das
et al. (2011, 2012) were more reliant on information from clinicians and staff
rather than service users. In addition, limited detail is given on the analysis
undertaken and the actual results found, meaning it is not always transparent
as to how they drew their conclusions.
