Mild Cognitive Impairment Clinical Trial
Official title:
Examining the Effects of a Brief Mindfulness Based Intervention (BMBI) on Mood and Cognitive Functioning in an Older Adult Population
The current study will examine the effects of a brief mindfulness based intervention (BMBI) on mood, memory and attention in comparison to a wait-list control (WLC) group. Participants for the study will be 90 adults aged 50 years and above who have presented at a memory clinic within SLaM NHS Trust with subjective cognitive concerns and/or those who have received a diagnosis of mild cognitive impairment (MCI) from their memory clinic.

Eligibility |
Inclusion Criteria:People aged 50 years and older with subjective memory concerns (SMC)
and/or those who meet criteria for amnestic mild cognitive impairment (MCI) who have been
seen by one of the three SLAM memory services (i.e. Croydon Memory Service; Southwark and
Lambeth Memory Service; and Lewisham Memory Service) in the past three months.
Participants must be able to give informed consent to participate. Exclusion Criteria: Diagnosis of dementia or multi-domain mild cognitive impairment, intellectual disability, current substance misuse, a current diagnosis of epilepsy or another neurodegenerative disorder (such as Parkinson's), a history of brain injury or stroke, a severe and enduring mental health disorder (e.g. severe depression or anxiety, personality disorder, schizophrenia, schizoaffective disorder, bipolar affective disorder), active suicidal ideation, severe sensory impairment that would significantly impair a person's ability to engage in the intervention. |

---|---|---|---|---|
Primary | Test of Everyday Attention | The Test of Everyday Attention (TEA): Two subtests from the TEA (Robertson et al., 1994) will be used in the current study. Specifically, the Elevator Test will be used to measure sustained attention and the Visual Elevator Test will be used as a measure of attentional switching, and hence of cognitive flexibility. The TEA subtests are based on everyday life scenarios offering greater ecological validity. It has parallel forms which allow for repeat administration within short time periods reducing the impact of practice effects. | Change in attention from Baseline to 1 Week | No |
Secondary | Hospital Anxiety Depression Scale (HADS) | The HADS consists of two subscales measuring depression and anxiety respectively. Each subscale consists of seven items and responses on the items are based on the relative frequency of symptoms over the past week using a four point Likert scale ranging from 0 (not at all) to 3 (very often indeed). Higher scores indicate higher levels of depression and anxiety, and scores of about 10 on each subscale indicate clinical significance. | Change in anxiety and depression from Baseline to 1 Week | No |
Secondary | Penn State Worry Questionnaire | Penn State Worry Questionnaire: The PSWQ is a 16-item measure of worry that has shown adequate internal consistency and convergent validity in elderly patients with GAD and controls( Beck et al., 1995 and Stanley et al., 2001). It uses a Likert rating from 1 (not at all typical of me) to 5 (very typical of me). | Change in worry from Baseline to 1 Week | No |
Secondary | Short Form Health Survey | Short-Form Health Survey (SF-36): The physical and mental summary scores of the Short Form Health Survey (SF-36) (Van de Zee et al., 1993) are used to measure quality of life related to physical and mental aspects. The SF-36 is composed of 36 items measuring health across eight dimensions: physical functioning, social functioning, role limitations due to physical problems, role limitations due to emotional problems, pain, mental health, vitality, and general health perception. These eight subscales can be summarized into one physical and one mental component summary score. Each dimension score ranges from 0-100. Higher scores indicate better health-related quality of life. | Change in quality of life from Baseline to 1 Week | No |
Secondary | The Trail Making Test Parts A&B | The Trail Making Test (TMT; Army Individual Test Battery, 1944) is a commonly used neuropsychological test of visual attention and task switching. It consists of 2 parts: part A asks participants to connect a series of numbers in ascending order on a page, while part B requires participants to draw a line alternating between ascending numbers and letters. Part A is used primarily to capture processing speed whereas Part B requires more complex attention shifting, planning, and concentration, and is, thus, considered a valid index of executive control. The time taken to complete the task is the primary performance outcome | Change in executive functioning from Baseline to 1 Week | No |
Secondary | Digit Span Task | Digit Span is a core working memory sub-test of the WAIS-IV (Wechsler, 2008). It requires participants to repeat a series of digits forwards and backwards with series ranging in length from 2 to 9 digits. This test also measures auditory sequential processing as the individual must recall auditory information and repeat it back aloud. The Digit Span subtest has revealed an average test-retest reliability of .82 (Wechsler, 2008b). | Change in working memory from Baseline to 1 Week | No |
Secondary | Letter-Number Sequencing Task | Letter Number Sequencing is a subtest of the WAIS-IV (Wechsler, 2008) and is a measure of attention and short-term memory. Lemay et al. (2004) report test-retest reliability data of between .73 and .75 in a two-week interval in middle aged to elderly subjects suggesting it can be reliably used in repeated neuropsychological assessments. | Change in working memory from Baseline to 1 Week | No |
Secondary | The Cognitive Failures Questionnaire | The Cognitive Failures Questionnaire (Broadbent et al., 1982) will be used as a measure of subjective cognitive complaints. The CFQ has been shown to have acceptable internal consistency and retest reliability, and good face validity in a sample of older adults (Knight et al., 2004). | Change in subjective cognitive concerns from Baseline to 1 Week | No |
Secondary | The Five Facet Mindfulness Questionnaire (FFMQ) | The Five Facet Mindfulness Questionnaire (FFMQ): The FFMQ (Baer et al., 2006) assesses five components of mindfulness: observing, describing, acting with awareness, non-judging of inner experience, and non-reactivity to inner experience. It has been shown to have good internal consistency (Baer et al., 2006) and adequate construct validity (Baer et al., 2008). | Change in mindfulness from Baseline to 1 Week | No |
Secondary | Ruminative Response Scale of the Response Styles Questionnaire | Ruminative Response Scale of the Response Styles Questionnaire (RRS of RSQ; Nolen-Hoeksema & Morrow, 1991). The RRS will be administered to assess participants' tendencies to ruminate in response to their symptoms of negative emotion. The RRS includes 22 items in response to depressed mood that are self-focused (e.g., "I think why do I always react this way?"), symptom focused (e.g., "I think about how hard it is to concentrate"), and focused on the possible consequences and causes of mood (e.g., "I think I won't be able to do my job if I don't snap out of this"), which participants rate on a scale from 1 (never) to 4 (always). Total scores range from 22 to 88 with higher scores indicating greater rumination. | Change in rumination from Baseline to 1 Week | No |
Secondary | Self-Compassion Scale Short-Form | Self-Compassion Scale Short-Form (SCS-SF): The SCS-SF (Raes, Pommier, Neff, & Van Gucht, 2011) measures self-compassion and it has the following sub-scales: self-kindness, self-judgment, common humanity, isolation, mindfulness, and over-identification. Participants have to rate how often they behave in a stated manner (e.g., "When I'm going through a very hard time, I give myself the caring and tenderness I need") in a scale from 1 (almost never) to 5 (almost always). Total scores range from 12 to 60 with higher scores indicating greater self-compassion | Change in self-compassion from Baseline to 1 Week | No |
Secondary | CORE-10 | CORE-10. The CORE-10 is a short, 10 item version of the CORE-OM, a standard measure of psychological distress | Change in general psychological functioning from Baseline to 1 Week | No |
Secondary | Discharge Satisfaction Questionnaire | The Discharge Satisfaction Questionnaire, (a standard service measure used within the MHOA CAG) will be completed by both the mindfulness and WLC group at post-intervention only to evaluate service satisfaction and the acceptability of the mindfulness intervention | Post-treatment | No |
