Officers feel the controversial policy of stop and search has been "disproportionately prioritised" over other police work, according to a report.

Her Majesty's Inspectorate of Constabulary in Scotland (HMICS) said some officers and staff in Police Scotland's Ayrshire division felt an emphasis on targets was having unintended consequences.

It found staff morale had been "adversely affected by the pace and nature of change" after the creation of the single police force in April 2013, mirroring the findings of a previous inspection of the Fife division in October.

HMICS identified "constant pressure to achieve performance targets" as a factor impacting morale and highlighted that there was no appraisal system in place for constables and staff.

The report said: "Whilst we acknowledge (key performance indicators) KPI and performance targets are strongly reinforced in the division, we noted that some officers and staff felt that the emphasis on targets had unintended consequences.

"An example provided by officers was the use of 'stop and search', which although valued by the organisation was felt by them to be prioritised disproportionately over other valuable police work that was not measured."

Morale was lowest for response and community teams and police staff, with the report identifying that staff cuts were affecting the ability of these teams to respond to calls.

Response times for higher priority calls had not changed, but had risen by an average of around 15 minutes over the past 18 months for lower priority calls.

"We are of the view that these are potential early indicators of increasing pressures on the division's capacity to respond effectively to demand," the report said.

Some officers and staff also expressed concerns about an increase in bureaucracy that was affecting their ability to manage individual workloads.

Complaints against the police had risen in the area but remained "relatively low", HMICS found.

Public confidence in local policing was high and antisocial behaviour and disorder had significantly dropped across the area.

However the number of people seriously injured on the roads increased by 17% between March and October last year, in contrast to an 8.3% reduction nationally.

HMICS has made several recommendations which call on Police Scotland to make progress on a consistent national approach to staff appraisal and ensure that statistical reports on police complaints are supplied to all local scrutiny committees.

The divisional commander is asked to review the roles of community and response policing teams, and take into account the views of officers and staff.

The Scottish Police Authority should also commission a planned Police Scotland staff survey "as soon as practicable" and ensure that it is done independently, the report said.

HM Inspector of Constabulary Derek Penman said the division was taking a "focused approach" to tackle the rise in serious injuries on the roads.

He said: "The division is not complacent in addressing crime and takes a problem solving method to tackle issues as they arise.

"They work well with their partners in the three local authority areas and their use of social media and the relationship between their campus cops and the young people from their communities are examples of good practice.

"But we found that opportunities are being missed for wider engagement between local officers and their communities.

"This may be linked to the consistent demands for community policing officers to support response policing and a review of this practice forms one of our recommendations to the divisional commander.

"Internal communication was an issue with some officers in Ayrshire expressing the opinion that Police Scotland currently is not upholding its own values in relation to staff and they sought more face-to-face communication with their senior officers."

The next HMICS report on Police Scotland's Aberdeen division will be published in May.

Chief Superintendent Gillian MacDonald, local policing commander for Ayrshire division, said: "HMICS recognises that Ayrshire division has delivered sustained reductions in crime, improved detection rates and significant reductions in incidents of disorder and anti-social behaviour whilst enjoying some of the highest levels of public satisfaction and confidence in Scotland.

"These are significant achievements and are testament to the hard work and commitment of my officers and staff to keeping people safe, and to the support of our partners and local communities, which is demonstrated in the range of partnership-working which takes place in and with local communities across Ayrshire every day.

"In addition, the report identifies a number of local examples of good practice, such as our recently introduced Prevention First partnerships in North and East Ayrshire, the award-winning Multi-Agency Domestic Abuse Response Team (MADART), our innovative use of social media to engage with communities and our successful Robbery Strategy and Spotlight sessions which support action to tackle problematic or emerging issues in our communities.

"The report also acknowledges that road safety continues to be an issue in Ayrshire, with more people injured on Ayrshire's roads in the last 12 months.

"It also recognises the impact of significant organisational change on officer and staff morale.

"I will take forward the recommendations, along with my senior management team, with a view to building on measures already in place to make improvements in these areas and to enhance and improve our local engagement."

Liberal Democrat justice spokeswoman Alison McInnes said: "This alarming report corroborates concerns from the Scottish Police Federation over a targets culture on stop and search in Scotland's national force.

"Local communities will be worried that police officers are being diverted towards using stop and search instead of tried and tested means that are more appropriate for their area.

"HMICS makes clear that this one-size-fits-all approach to policing is having a direct impact on the morale of frontline officers.

"It seems to flatly contradict the Chief Constable's suggestion that there is no targets culture.

"A targets culture isn't fair or fitting for police officers or the communities they serve. It is overdue that Chief Constable listened to these voices."
