Evidence Base Camp: Day 2

Transcription

1 Evidence Base Camp: Day 2 Practical Group Sessions Graham Cline National Police Library Mark Abram Research Unit Charmian Werren Research Unit

2 Research question What interventions have been shown to be effective in supporting individuals during an acute mental health crisis?

3 Session Outline Practical session Walk through of an example search Develop search terms for our question area Look at each tier of our search in turn Run search of combined terms

4 Recap

5 The process (in a nutshell) 1. Draft search terms/run searches 2. Draft sift criteria 3. Sift received abstracts 4. Request full papers 5. Read and grade papers 6. Write it up ( synthesis )

6 Terms Results Anywhere in the article Domestic violence 597,000 Domestic abuse 32,500 Title only Domestic violence" 23,700 Domestic abuse 1,220 Published since 2000 (title only) Domestic violence" 13,200 Domestic abuse 822 Adding randomised controlled trial Domestic violence" 0 Domestic violence" 0 Search terms are hugely important Today s session will really focus on our search terms and their impacts.

7 The Basics Boolean operators Boolean is a powerful tool and can be used to create quite complex searches. The standard Boolean operators are: AND OR NOT (or AND NOT) (advanced users only!) Boolean is most effective when used in combination with: PARENTHESES (round brackets) TRUNCATION e.g. politic* WILDCARDS e.g. randomi?e DOUBLE QUOTES for "specific phrases" 10:45

8 Practical example of searching - What works in preventing residential burglary?

9 Creating a search string example of domestic violence

10 Creating a Search String String should be based around the research question: What works in the policing of public order? How can we reduce recidivism amongst sexual offenders? Each key aspect identified will then make up one Tier of the search. The tiers will then be combined to create the complete search string.

11 Tiers There are often three tiers, but there can be as many or as few as the search requires. The standard way to create tiers is create lists of synonyms within a table, eg. Tier 1 Frozen Dessert Ice cream Froyo Sorbet Grannita Tier 2 Wafer Wafer Waffle Tier 3 Syrup Golden syrup Maple syrup Chocolate sauce Strawberry sauce

12 Domestic violence example Q: What are the risks/ predictive factors associated with domestic violence/ abuse? Tier 1. Domestic violence / Domestic abuse This is the main area of the search. Tier 2. Risk factors/ predictive factors These terms interact with the main subject of the search. Tier 3. Effectiveness / What works We want to capture evidence that is evaluative, rather than commentary. Tier 4. Policing (?) We may want to limit our search to factors for the police and policing, or we might decide we are interested in factors identified from healthcare or other potential partners.

13 Building our search string using synonyms Q: What are the risks/ predictive factors associated with domestic violence/ abuse? Tier 1: Tier 2: Tier 3: Tier 4: Domestic violence/ abuse Risk/ predictive factors Effectiveness Policing Domestic violence Risk assessment Evaluation Police Domestic abuse Risk management Assessment Policing Intimate partner violence Risk appraisal What works Law Enforcement Intimate-partner violence (hyphenated) Intimate partner femicide Spousal assault Partner violence Battered women Wife assault Risk of homicide Prediction of homicide Nursing assessment Lethality risk assessment Predicting/ predictive Dangerousness assessment Impact Randomised controlled trial Trial Experiment Systematic review Repeated violence Couple violence Domestic murder

14 Turning synonyms into search terms ((Domestic OR Physical OR Emotional OR Familial OR Marital OR Spousal) AND (Abus* OR violen* OR control* OR behav*)) OR Coerc* OR "domestic homicide" OR "marital rape" OR "intimate partner violence" OR "repeat victim*" OR "women s refuge" C. 197,000 results 11:30 - break

29 Tier 3 - Version 1 - ProQuest Search terms (crisis OR crises OR emergency OR hysteria OR acute OR attack* OR episode*) Approximate number of hits 1 million

30 Tier 4 Synonyms interventions Insert Established Terms for Tier 4 Police police OR policing OR "law enforcement"

31 Tier 5 Synonyms What Works Insert Established Terms for Tier 5 WHAT WORKS ("systematic review" OR "literature review*" OR trial* OR "RCT" OR experiment* OR evaluat* OR "best practice*" OR "good practice*" OR effective* OR assess* OR "What Works" OR impact* OR success*)

32 Initial merging of terms Version of Tier 1 + Version of Tier 2 = c. records + Tier 3 = c. records + Tier 4 = c. records Issues/ questions/ queries What surprised you, etc.

33 This exercise 1. Shows the value of systematically searching 2. Shows the impact of having multiple tiers in our searches 3. Gives us an idea of the number of articles that might be relevant to our research question At the next evidence base camp we will sift through the abstracts based on inclusion/ exclusion criteria to identify the full papers to request for the review.

34 Usual Synonyms intervention* OR tactic* OR strateg* OR initiative* OR procedure* or approach* ("systematic review" OR "literature review*" OR trial* OR "RCT" OR experiment* OR evaluat* OR "best practice*" OR "good practice*" OR effective* OR assess* OR "What Works" OR impact* OR success*) police OR policing OR "law enforcement"

35 Back-up Synonyms " mental health crisis " OR "psychotic episode*" OR "extreme anxiety" OR " panic attack*" OR (suicidal AND (behavio*r OR intent)) crisis OR crises OR emergency OR hysteria OR acute OR attach OR episode* or trauma?
