Brief summary
The purpose of this research study is to examine the effectiveness of an online Spanish cognitive intervention program in Latino/Hispanic Spanish-speaking subarachnoid hemorrhage patients. In particular, the researchers will examine whether cognitive impairments associated with a subarachnoid hemorrhagic event improve after completing the online cognitive intervention program. Secondary outcomes of the research study include examining whether there is an improvement in research participants' quality of life and psychological functioning as a result of the online Spanish cognitive intervention program.
Detailed description
40 Spanish-speaking research participants who have sustained a subarachnoid hemorrhage in the last 6 months will participate in the current research study. Participants will be randomly assigned to one of two groups: 1) Cognitive intervention group (n = 20) or 2) Control group (n = 20).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| FAS (Lezak, 1995; Pontón et al., 1996; O'Bryant et al., 2017; Benton, Hamsher, & Sivan, 2000) | 16 months | This is a measure of lexical fluency abilities. Participants are required to generate as many words as possible within 60 seconds with the letters F, A, and S. |
| Escala Wechsler de Inteligencia Para Adultos-IV (WAIS-IV; Wechsler, 2008) Retención de dígitos | 16 months | This is an oral measure of working memory and attention abilities. Participants are presented with a series of numbers and must repeat them correctly in forward, reverse, and sequence order. Score values range from 0-to-48. These are considered participants' raw scores. Raw scores will then be converted to scaled scores based on available published normative data. All converted scores will be presented as scaled scores with a mean of ten and standard deviation of three in order to ensure that all scores are on a uniform scale. Scores falling at 1.5 standard deviations below the mean (scaled score ≤ 5) will be considered impaired. Scores that are above the 1.5 cut-off (scaled score ≥ 6) will be considered to be intact. Intact scores will be indicative of better outcomes on working memory and attentional abilities. |
| Color Trails 1 and 2 (D'Elia, Satz, Lyons-Uchiyama, & White, 1996) | 16 months | These two tests are non-verbal timed measures that assess processing speed and executive functioning abilities. Color Trails 1 is a sequencing test in which participants draw a line connecting numbers scattered throughout the test stimuli from least to greatest as quickly as possible. In Color Trails 2, participants are required to do the same as in Color Trails 1, but they must alternate colors for each number sequence as quickly as possible. |
| Spanish Rey Auditory Verbal Learning Test | 16 months | This is a commonly used comprehensive verbal learning and memory test. The test consists of a 15-item word list that is presented five times. Participants are then asked to recall as many words following a brief delay and 20 minutes later. Raw scores from the following scales will be utilized: Total Recall, Short-Delayed Free Recall, Long-Delayed Free Recall, and Recognition Hits. Score values range from 0-to-15. These are considered participants' raw scores. Raw scores will then be converted to scaled scores based on available published normative data. All converted scores will be presented as scaled scores with a mean of ten and standard deviation of three in order to ensure that all scores are on a uniform scale. Scores falling at 1.5 standard deviations below the mean (scaled score ≤ 5) will be considered impaired. Scores that are above the 1.5 cut-off (scaled score ≥ 6) will be considered to be intact. Intact scores will be indicative of better memory outcomes. |
| Escala Wechsler de Inteligencia Para Adultos-IV (WAIS-IV) Claves subtest | 16 months | This is speeded graphomotor transcription subtest that assesses attention and processing speed abilities. Participants are required to a place a code with its designated number as quickly as possible in 120 seconds. Score values range from 0-to-135. These are considered participants' raw scores. Raw scores will then be converted to scaled scores based on available published normative data. All converted scores will be presented as scaled scores with a mean of ten and standard deviation of three in order to ensure that all scores are on a uniform scale. Scores falling at 1.5 standard deviations below the mean (scaled score ≤ 5) will be considered impaired. Scores that are above the 1.5 cut-off (scaled score ≥ 6) will be considered to be intact. Intact scores will be indicative of better outcomes on processing speed and attentional abilities. |
| Animal Naming (Lezak, 1995; O'Bryant et al., 2017 | 16 months | This is a measure of semantic fluency abilities. Participants are required to generate as many animal names within 60 seconds. |
